Hi guys,

I've been using OpenVZ for months and until now it's been working perfectly.

Then a few days ago, I was unpacking a tar ball on one of the VEs and suddenly it dumped, causing a kernel oops:

homer kernel: Oops: 0002 [1] SMP

The tar process turned into a zombie and any subsequent that tried to access the last file created also zombied (like ls or vi.) I couldn't use ps any more either, again the process turned zombie. After a reboot everything was back to normal but I had to do a hard reset since the harddisk did not want to sync either.

I haven't been able to reproduce the error so far, but I wanted to report it any way.

$ uname -r
2.6.18-1-openvz
