Yes. The other machine with 2.6 kernel also have vservers but with much
lighter usage

Ok, so do you think vserver IS the culprit, because of a bug in vserver
2.6 memory allocation code, Or (much more probable)
vserver just triggers the bug because the vservers, in a cumulative
effect are BIG consummer of memory ?
In that case, vserver is not the bug owner, it's the 2.6 kernel in
itself that have defficiencies in that case...

Maybe time to buy an opteron system :) Or just see the 2G/2G option I
already seen discussed in linux kernel mailing lists...
And posting in linux kernel mailing list.

Thanks for your response...

Oh, btw, You may be interrested by the fact we have now more than 100
vservers deployed... Thanks again (you & others) for this
very nice piece of software...
