Hi,

So i downloaded the older miltermodule.c module and recompiled the 
debian package, but we still get the segfaults.

I am attaching some pieces of output from logs when the segfault 
happens. It seams that it happens when calling close methods from 
different threads one after the other. But i don't now if this is the 
problem.
