Hello Christoph,

do you think it could be a compiler problem? I still can't imagine why
only 2 people have seen this (at least it wasn't just me), but it
_always_ hits with newer kernels on that node.

Right now, I'm trying the problematic release, compiled with a newer
gcc (4.9.2-6 from Fedora, while using 4.4.7-11 from rhel6
before). It has only been running a few hours yet, so I can't tell if
it's good.

Regards,
Torsten
