[cobalt-users] [RaQ4r] Server stops accepting new network connections suddenly.

[Moritz Julian Ehlenz <mjehlenz@xxxxxxxxxx>]

Hello everybody,

since about a week ago we are experiencing severe problems with
one of our cobalt raq servers. The server just stops accepting
new network connections several times a day. If I am still logged
in using ssh, I can use top to check the load on the server etc.
After a while the server resumes normal operations as if nothing
had ever happened. If I reboot the system during those times it resumes 
normal operations after startup.

The problem is definetely not related to the logrotate process since 
usually it's not even running when the problems occur. The load isn't 
any higher than usual either. The problems are also not related to 
general network problems since I can work on the machine w/o any 
problems when I have logged in before the start of the problems. 
Furthermore I have a whole bunch of servers running w/o any problems on 
the same connection in the same subnet.

I'd really appreciate it, if anybody would share his ideas on what could 
cause these problems. TIA

Regards,
Moritz
