Hello there
I run and openvz based system for 14days now.
Yesterday this starts :
[root]# Nov 29 10:06:30 MYSYS kernel: Negative vm_rss: process pid 20999 comm avbasestest flags 4, vma e35c76f4 b7b26000-b7b43000 00000000 rss 1 freed 29

Now the system crashed all vm's. Only a reboot of the hardwarenode was helpfull.
This is reproduceable while updateing aveserver-signatures.
HW-Node is running RH-Enterprise 4 2.6.9-023stab032.1-smp #1 SMP
VPS is running debian-sarge.
Can you give me hint what causes this crash.
Best rema.
UPDATE: user_baencounters of the vps running the aveserver-prozess
