thanks for the hint. I saw this thread and the proposed fixed and tried 
to fix the bug. But, as mentioned, this did not work, even disabling 
pthreads completely did not fix the problem. It seems, like this issue 
is not related to my issue, although the problems described in this 
thread (and ticket 285) are similar to mine.
Furthermore does my issue appear with TCP as wells as UDP.
