One needs vzbulk and generic.sh which is included by vzbulk.

Here http://sunoano.pastebin.com/m70daa95f is what it looks like if two barries for the VE with VEID 3003 got hit. Then you know exactly which VE and what resource you have to thouch in order to make that nasty error message go away.

Otherwise (without vzbulk) you would have to manually check every VE on the system ... that's in O(n) ... pfff ... no thanks but thanks

As you can see you don't have enough memory, heck you don't even have swap space, I suggest you turn off amavisd and clamd both of which hogs memory not that much but given the amount of memory you have it's best to turn off those services, caveat though is you can't do any content filtering.

you need stop the clamd and amavisd. but remember, the dkim would not working.

chkconfig --level 3 clamd off
chkconfig --level 3 amavisd off

service clamd stop
service amavisid stop

edit /etc/postfix/main.cf
comment  the content_filter line

content_filter

then reload postfix
postfix reload
