Hi Ingo,

After some debugging, this looks like a memory management error in ip-mib code.
It looks like an container entry is freed, but still used in another container.
As soon as the memory is reused, the entry is corrupted and accessing the second
container will cause a crash.

I'll check how to fix this (maybe by using some updated mib code from upstream).

Thanks,
Jochen
