lot of cpu power in terms of processes or CPU usage? a single process only adds +1 to the loadaverage > After about 10 min the load is 700 , after 15 min 750-800 and after > 20 min nothing can be done on the server. sounds like something 'forking' up to 800 processes or more, which for sure will take down a linux server using 2.4.xx ... > The server and the vservers answer a ping and the ports are > still open, but it accepts no connections. I'd suggest checking _which_ processes are started and why, if you system really needs 800+ processes, then you should consider switching to RR scheduling or move to a 2.6 kernel, which might handle them more gracefully but most likely some 'condition' is met, which the broken? software interprets as 'oh my god, my thread died' and reacts with 'quick, let's start another one' you can get the same result by starting an unlimited fork bomb on one server (or on the host) HTH, Herbert _______________________________________________ Vserver mailing list [EMAIL PROTECTED] http://list.linux-vserver.org/mailman/listinfo/vserver
