I hope, that this will work.
What irritates me:
I did tests with deactivated quotas on system and disk, but the problem
remained.
We don't have the problem with Oracle Linux (RHEL), which uses regular kernels

Curently it's not working because of some missing dependencies.
Is it much work, to put the missing modules to the testing repository?

Hello Lucas,
I don't really want to compile an older Samba version or install

So do you know any backport repositories with these versions?
