I noticed an intermittent slow response on the ping from my application server to my database server. So to diagnose, I tested using a standard ping and Telnet tests.

For the telnet tests, it was able to connect. However some telnet took longer to connect than others.

For the ping, I noticed that I am missing a lot of icmp_seq. It was skipping occasionally. On the other server, it was communicating very sequentially.

But for the app to web and app to app, there were no skipped items. From the app to DB there is.

Anyone have any idea on what is happening ?

Just to add, the database response was very intermittent as well. Sometimes slow. The application server and database are on different network segments as well.

What can we look at ?

I have a system that is running out of memory and has a lot of open connections. but my swap space is not being used up that much.

Can socket/socket file descriptors use swap space?

This is for a linux system btw.

Thanks

How do I check if a port is consistently alive? For example, I could use

ping 192.168.1.1 -t > results.txt

This will ping 192.168.1.1 continuously so that I could monitor it.
Is there an equivalent tool or command that I could use for this?

Currently I use telnet but sometimes the host disconnects it. I need a Windows solution.

What is the best way to backup millions of small files in a very small time period? We have less than 5 hours to backup a file system which contains around 60 million files which are mostly small files.

We have tried several solutions such as richcopy, 7z, rsync and all of them seems to have a hard time. We are looking for the most optimal way...

We are open to putting the file in an archive first or transferring the file to another location via network or hard disk transfer

thanks
