Hi,

I have several containers running fine on CentOS 5.
Now I have migrated them to a new machine running CentOS6 with kernel 2.6.32-042stab072.10

In the new host most (not all) the containers suddenly have dcachesize increased up to the limit with no apparent cause.
Inodes and disk quotas are fine.
If I use vzcfgvalidate it asks me to increase dcachesize by 10 times, but if I do that right after rebooting the CT it reaches limit again.

In one of them numpty increases automatically to the limit, too.

Any idea of what may be causing this?
The containers run smoothly, everything works but I have this strange behaviour.

Do you see something strange on this beancounters?

Thanks!

I have the same problem with 'dcachesize'. My kernel version is 042stab075. I've read that some time ago there was a bug in the kernel version and there was some leaking related, but I suppose i was fixed

any suggestions?
