We have an Azure logic app that fires every 60 seconds. It fetches a URL. Typically this would only take < 1s, but sometimes if there's a lot of work to do on the other end it can be higher.
Will the Azure logic app service wait to fire again if the previous request is still pending or will it just fire again regardless?

We're using Windows Server 2012 R2 Datacenter, is there any way to stop this exception from a server config point of view in any way at all?
This is a funny one that's just started happening. Changes I've recently made:
Site otherwise has been untouched for many many weeks (perhaps months).
All re-written URL's seem to be affected. The URL's work fine for a while, then all of a sudden we start getting:
404 directory not found
On these URL's. I can't for the life of me work out why this is, and what's causing it. Event viewer doesn't seem to show anything relevant.
Rebooting server fixes it temporarily, as does restarting IIS. Recycling app pool sometimes works temporarily.
Server
Windows Server 2008 R2
Latest updates
Website target framework 4.5.2
IIS 6.1 Build 7601 SP1
IIS app-pool framework 4.0
Single application app-pool (not shared)
Does anyone have any ideas on what could be causing this, or how to investigate further? This could start hurting us badly. Any help much appreciated.

Our blob storage is crucially important to our business. If for some reason one day the blob storage account is deleted from hackers or buggy scripts, it would cause serious harm.
What's the best way to backup blob storage to mitigate against an attack where for example someone logs in to our Azure portal and just deletes everything they see? Simply backing it up to another region wont protect against that sort of damage.
The situation we're finding ourselves in is:
Serves www.example.com
Serves www.widget.com
For various technical reasons, we are unable to unify the sites into a single host. What we'd like to do, is make:
www.example.com/widget
Serve Webhost #2's content (dropping the domain www.widget.com). Ideally, making example.com/widget have a CNAME record point to #2's IP would be ideal, but I know this is not possible.
Are we able to make a subfolder in a URL point to another host without redirecting to subdomains? We need the URL structure to remain natural (no subdomains).
Proxy's are not an option, as the two environments are geographically very far apart. (Again, for a variety of technical reasons).

We are currently moving from one server to another.
I'm new to DNS and server admin which isn't ideal I know! This is how our current working domain is set up for email with Google apps:
http://www.intodns.com/scirra.com
In preparation for moving server and changing nameserver I've created this zone on zoneedit (the current nameserver isn't with zoneedit):
And this is what the DNS looks like on the new server:
What I would like to know is when I point the domain to the new nameserver with this setup will the mail server be uninterrupted? We can't afford much downtime at all for email.
One thing I have noticed is the IP in one TXT entry refers to our old (current) servers IP which of course needs changing, but will this break the email in any way if I just modify that entry? For example, does Google need to be notified of this change at all or will it happily just pick up the changes?
We're in the process of moving from one server to another.
I'm running the SQL Server database off our new server, with the old server now using that as a DB server with the aim to make it a smooth transition from one server to the other whilst DNS propagates so no down time for anyone.
Nothing else is currently running on the new server, it's a fresh install of everything.
The sqlserver.exe process seems to be increasing in memory requirements non stop, is this most likely to be connections not closing properly on my website? Or are there any known memory leaks in SQL Server? We receive around 40k page views a day, and probably around 5x that number in crawler pageviews.
Total DB MDF+LDF size is quite small, only 600mb. The current commit (KB) of sqlservr.exe is 2,393,000. It's increasing at a rate of about 0.5MB every second or two.
If this is connections not closing properly on our website is there any way to clean old open connections? Apart from obviously fixing the root cause what can we do in the meantime?
I'm on Windows Server 2008. I'm using intoDNS to check I'm setting my DNS up correctly:
http://www.intodns.com/wewantogg.com
Everything looks fine for this domain except for the notice:
INFO: GLUE was not sent when I asked your nameservers for your NS records.This is ok but you should know that in this case an extra A record lookup is required in order to get the IPs of your NS records. The nameservers without glue are:
209.126.137.108
209.62.64.46
You can fix this for example by adding A records to your nameservers for the zones listed above.
The name servers for this domain are:
ns12.zoneedit.com ['209.62.64.46'] [TTL=7200]
ns14.zoneedit.com ['209.126.137.108'] [TTL=7200]
I've added them as a forward lookup zone in my servers DNS manager:
Is this correct? It's still saying glue records have not been found and I'd like to resolve this if possible.
We move from this server:
SQL Server Express R2 (has a 1CPU/1GB ram limit as far as I'm aware)
2GB Ram
2 core 2.1ghz
To this server:
SQL Server R2 Enterprise
8GB Ram
4 core 3.2ghz
Everything seems to be working fine. Our MDF and LDF files for the database combined are around 600mb (we only run 1 database).
I've looked at some memory options for the server and see that our database has a minimum server memory set to 0MB, and a maximum of 2147483647MB. Use AWE to allocate memory is off.
Would we benefit by adjusting these values at all? Out of the 8GB ram, we have 5.5gb free. We still have to install a web app on the server but that doesn't use much at all.
We had smarter mail installed, but it kept wiping/corrupting all our email. This was problematic to say the least.
Anyway, finally we decided to move and are now using Gmail. We have all our DNS setup and are using Gmail just fine! It's brilliant and we love it.
We then uninstalled Smartermail.
Now we have a couple of mailing lists, some with just over 2,000 people on them. We can use Gmail to send mails out, but this exceeds the 2k daily send limit.
Is it possible to install another SMTP program on the server to send mail? We don't want to receive, just use it to send. I'm a bit clueless as to what to do here, we're using ASP.net and C#, can we use our server to send email without going through Google?
Really having trouble with this, I've been through all the guides I can find and get stuck, using latest version of Smartermail 8 on Windows 2008 with IIS7.5.
I have it setup so I can SEND emails fine, and login etc, but it just wont RECEIVE emails. I always get this back:
Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 Unable to relay for [email protected] (state 14).
I followed this guide:
http://portal.smartertools.com/KB/a31/cant-receive-mail.aspx
And got these results, which make little sense to me. I've also included some images of my setup, if someone can spot the obvious fault?
When I do: netstat -abnp tcp
I get only one listening on port 25:
TCP 127.0.0.1:25 0.0.0.0:0 LISTENING
My smartermail web server config is set to all IP addresses on port 9998, I've tried 25 as well but not luck. SMTP service is stopped in services as well.
Any help greatly appreciated, I don't understand much of this.
Is this now correct?
MX records look like they are set up correctly. Still it's bouncing with same message.
Some people say I need to disable SMTP Service, others say leave it running. When I:
telnet 84.45.57.142 25 I get the response 220 tom.scirra.com Microsoft ESMTP MAIL Service This is with the SMTP service running.
When SMTP service is NOT running I get the response:
Could not open connection to the host, on port 25
When I netstat -abnp tcp I get TCP 127.0.0.1:25 0.0.0.0:0 LISTENING [MailService.exe]
But stuck on this one, looked on google but couldnt find anything.
The deployment of the site went slightly wrong and some pages were being saved as:
Where the IP was the underlying IP address for the domain (so the pages served fine).
Now however, lots of crawlers are indexing the IP site, AND the main site. This is a waste of bandwidth and causes some duplicate content issues!
How can I redirect the IP to the domain?
We have a website, with a file:
www.example.com/apis/httpapi.asp
This file is used by the site internally to make requests joining two systems on the website together (one is Classic ASP, the other ASP.net). However, we do not want the public to be able to access the file.
In IIS7.5, is there a setting I can do to make this file internal only? I've tried rewriting the URL for it but this rewrite is also applied internally so the scripts stop working as they fetch the rewritten url.
Thanks for any help!
