Hi there,
This morning i detected a serious problem with the apache server on multiple vps's and i don't know exactly were is the problem.
Before i used OpenVZ to make a vps based webhosting environment i was using shared hosting and this problem didn't occur.
On several vps's the apache process died without any resource beind exausted. The apache error_log says:

[Mon Oct 16 00:39:34 2006] [notice] SIGHUP received. Attempting to restart
I've checked the user_beancounters file and i don't have any failcnt's.
The site hosted is a simple one, html based, no php or other dinamic page generating language.
After some googleing i only found answers about this problem related to a php extension but not anything else 
Maybe someone here has stumbled on this one before me and could give me some hints 
EDIT:
After some checking i discovered that ALL apache servers are dead since 8:36 this morning !
They all ended operations with the following message:
[Mon Oct 16 08:36:59 2006] [notice] caught SIGTERM, shutting down
And i didn't shut them all down, the vps's were all up but the apache servers all down and all the logs have the messages posted above in them
