We are a some devs working on a Debian server. We are all connecting from one IP.
So basically the server handles a lot of requests from the same IP. Now what happens from time to time, is that we get a timeout. It feels like fail2ban, if you input the wrong password for several times. But it's not.
There is no firewall restriction on ports or sockets.
Could it be some kind of kernel maximum to TCP/IP connections? top says that there is no strain at all. (cpu, ram etc...).
The web-server is an AOLServer. There are definitely no issues with it.
Version: 6.0.7 Debian
The same goes for SSH as you can see it's not application related but rather OS related.
We all use Debian as clients as well. If people connect from a windows machine there aren't problems.
Thankful for all suggestions. Let me know if you need more information.
