I moved a friend of mine off my root server onto another vserver as he was eating too many resources. The vserver is using a minimal Debian 5.0 32bit image from server4you which I have upgraded to 6.0 He is on the smallest vserver available from server4you and CPU and RAM consumption is negligible. Traffic is minimal but it seems that his periodical newsletter is making him hit some limits. And I need to add, I haven't even started sending the newsletter, currently still configuring and tweaking, sending some test emails, etc. currently it looks like this: Code: grep -v ' 0$' /proc/user_beancounters Version: 2.5 uid resource held maxheld barrier limit failcnt lockedpages 0 336 344 344 560 tcpsndbuf 160984 2446744 2449232 3598712 142 othersockbuf 244440 748296 744366 1481926 392 numothersock 140 288 288 288 23398 there isn't much running on the machine, I tried to keep it lightweight: Resource usage is minimal: there are hardly any visitors to the website and its running on nginx so I think that is not the problem. Same goes for mysql. I tried lowering postfix, dovecot and saslauthd to minimal processes/threads as far down as I could but I am not sure I am succeeding... Is there any way to figure out, what makes me hit the limits I see in the beancounters?
