Hi, all, Recently I constantly met segmentation fault for my django server(started by runserver). The following is the trace I got from gdb (if not with gdb, I only can see segmentation fault). I knew this may not be a django issues, or even python issue, but anyone met similar issues or where I should ask? Thanks a lot:
