Connections hanging

5 posts in this topic

I've got a dedicated server that I recently purchased. I've disabled a few things that originally came with the server that I knew I would not be using, chilisoft ASP engine, and real media server.

Now for some reason I'm having really long connection times. It takes me about 90 seconds for me to actually login to the box via ssh.
FTP connections almost always timeout.

After a fresh restart, things are much more responsive but after about 12 hours of up time, it starts grinding to a halt.

Apache is not being effected tho. I'm not sure what would cause this but it is sure a pain in the ass.

Any ideas?

Since you mentioned chilisoft ASP engine im going to assume this isnt a Windows server, but maybe posting some extra details like OS, network setup etc might help. Depending on how many users it could be network congestion. Or maybe some process taking up all resources. Even though i dont have a huge amount of experience with anything other than home servers I would start by looking at whats running while it hangs (try doing locally if you cant do ssh) and working my way from there.

It seems like processes just sit there after they have run their course but don't actually get killed.

The could be symptoms of a ton of things. Ping the server and post what kind of results you get.

It's responding to pings perfectly well. I've had one running for a couple hours:
[code] Packets: Sent = 11329, Received = 11314, Lost = 15 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 91ms, Maximum = 378ms, Average = 107ms[/code]
