After 4 months of perfect work my server with opensuse 11.4 started to freeze. When I'm trying to login into it from another server in the same network I get just the following message:
Last login: Sat Sep 10 23:17:38 2011 from blablabla
Have a lot of fun...
and nothing else. From my home pc I can't even get connected with it, just form the neighbour server.
I have 16 Gb of ram and don't believe that swap gets full..Also I have cron job, that is running every 2 min and killing those processes that are using more than 90% of cpu. So it shouldn't be the overload issue either..
Could somebody explain such server behaivior and how to find the cause ? (no error logs)
