After upgrading my system, a program started to throw this error, and
make a core dump:
Fatal Python error: ceval: tstate mix-up
Kernel log says:
Jan 9 05:06:49 shopzeus kernel: pid 89184 (python), uid 1024: exited on
signal 6 (core dumped)
I found out that this can happen only when executing Python code without
holding the GIL. My program is written entriely in Python, but uses some
third part libraries:
py25-json
py25-psycopg2
Here is Python version:
Python 2.5.2 (r252:60911, Nov 17 2008, 22:19:20)
[GCC 4.2.1 20070719 [FreeBSD]] on freebsd7
(OS is FreeBSD 7.0 amd64 stable on dual quad core xeon 5420, it that
matters...)
I have the code dump, but I do not know how to debug that. What should I do?
Thanks,
Laszlo
