I requested an hard reboot because none of ssh and http worked. Ping worked normally.
Which logs should i check to understand what was the problem?
Thanks! (debian 6 on lamp)
Edit: my memory and swap:
Mem: 4040068k total, 1114920k used, 2925148k free, 109212k buffers Swap: 1051384k total, 0k used, 1051384k free, 283820k cached
4 GB ram
(and more than 1TB of HDD)
The cause is from 2 days ago:
look how the usage of swap goes +60% in less than 10hours
My control panel reports this as top 5 memory usage process:
If every apache2 process is 190MB large that sux because IF i do TOP i have 262 sleeping process most of them are apache2!
My apache mpm_prefork settings are:
<IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 ServerLimit 1500 MaxClients 1500 MaxRequestsPerChild 2000 </IfModule> KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 4
