I want to use an existing topic as I am also getting Call Traces errors. Attached you can find diagnostic files.
From the system log I can see errors like this:
python[12239]: segfault at 2aadb4b2dff8 ip 00002aadb00d96d1 sp 00002aadb4b2e000 error 6 in libpython2.7.so.1.0[2aadb006b000+342000]
and call trace like this

Do you have any idea what is causing the errors?
