Some people have reported problems with Python, closer research showed that these problems were not with openMosix but rather with glibc issues, however it seemed that issues manifested themselves especially in openMosix.
One user solved the problem by removig /lib/i686/lib* on his machine and let the applications link dynamically against /lib/libpthread (and other) However bugfixes in newer glibc versions combined with more recent openMosix version seem to have solved these problems.
