vzctl chkpnt --dump --dumpfile xxx.dump => Kernel says "Holy Crap"

Hello !

When doing a dump of a container, I have some stanges errors in kernel.log :

May  9 01:46:55 www kernel: Holy Crap 1 0 12176,1120(imap-login)
May  9 01:54:25 www kernel: Holy Crap 1 0 4487,291(pdns_server)

May  9 20:11:39 www kernel: Holy Crap 1 0 8978,331(opendkim)

Script does this :

1) Rsync (first pass)
2) vzctl chkpnt xxx --suspend
3) vzctl chkpnt xxx --dump --dumpfile "xxx.dump"
4) Rsync (scond pass)
5) vzctl chkpnt xxx --resume

I have found the file where this error come from but I do not understand the source. (Line 279)

Re: vzctl chkpnt --dump --dumpfile xxx.dump => Kernel says "Holy Crap"

I have the same problem on my server:

root@wfsr010:~# uname -a
Linux wfsr010 2.6.32-11-pve #1 SMP Wed Apr 11 07:17:05 CEST 2012 x86_64 GNU/Linux

root@wfsr010:~# vzctl
vzctl version 3.0.30.2-11.git.aefc8ef



I think this problem appeared while trying to migrate a CT, although I am not sure (and anyway the migration fails due to an other error):

Please can you test with the latest kernel from the 'pvetest' repository?

Did you ever find the reason behind the "Holy Crap" log entry?

I have a similar problem with openvz online migration and this appears in my logs too.

no, I live with it... It doesn't seem to have any really bad consequence.
