This was totally an isolated incident, but I performed this command:

ping 192.168.1.134

and got this result [image]:

Pinging 192.168.1.134 with 32 bytes of data:
Reply from 192.168.1.133: Destination host unreachable.

note the .133 in the first 'unreachable' reply. I guess I don't understand how this is possible - even given a totally crazy coincidence.

On three separate occasions on two separate servers at nearly the same times, 6.9 hours seemingly went by without any data being written to the IIS logs, but, on closer inspection, it appears that it was all recorded all at once.

Here's the facts as I know them:

• Windows Server 2003 R2 w/ IIS6
• Logging using GMT, server local time GMT-7.
• Application was still operating and I have SQL data to prove that
• Time gaps appear in log file, not across two

• headers appear at gap

• Load balancer pings every 30 seconds
• No caching

Here's info on a particular case:

• an entry appears for 2009-09-21 18:09:27
• then #headers
• the next entry is for 2009-09-22 01:21:54, and so are the next 1600 entries in this log file and 370 in the next log file.
• about half of the ~2000 entries on 2009-09-22 01:21:54 are load balancer pings (est. at 2/min for 6.9hrs = 828 pings)
• then entries are recorded as normal.

I believe that these events may coincide with me deploying an ASP.NET application update into those machines.

Here's some relevant content from the logs in question:

... back to normal behavior

Note the seemingly correct date/time written to the #header of the new log file. Also note that /ping.aspx returned 404 then switched to 200 just as the problem started. I rename the "I'm alive page" so the load balancer stops sending requests to the server while I'm working on it. What you see here is me renaming it back so the load balancer will use the server. So, this problem definitely coincides with me re-enabling the server.

Any ideas?

I want to start using SQL Server 2008R2, but I need to also be able to deploy my apps with databases to SQL Server 2008. I just found that I cannot backup 2008R2 to restore 2008. Why? What are my options?

I can kinda understand the forward only compatibility when we went from 2005 to 2008, although I still found it annoying, but I don't see why it had to happen on this .5 release.

What can I use to monitor my Rails on Passenger on Apache on CentOS web app?

I'm looking for something simple that will let me see real-time info on average requests/sec and average request time. Ideally, it would let me view that historically.

I'm looking for a SharePoint (MOSS) shared hosting provider that supports deployment of custom solutions (.WSPs) - it'd be okay if it was medium trust. I'm building a public Internet site on SP and the client doesn't want to host it or pay for the license all up front. Any suggestions?

[Previously asked on SO - no good answers then]

Is there a service that will identify where a site is hosted (presumably by IP)?

I want to use SQL Server 2008, but I'd also like to maintain a fall back position of switching back to SQL Server 2005. I know I cannot backup 2008 to restore 2005 and detach/attach won't work - what are my options?

[Update] To those asking why, two reasons -- one to develop from, where I can have access to 2008 features, but if a problem comes up or I don't find them useful enough, I can put my app back on 2005 and two, for run time so that if I find late in the game an unexpected problem.
