It is. I was using 5dim's side inserters that was causing it to crash when I used them often. Haven't had any issues since I stopped using them.

Might have to tell the mod author about it.

I'm not sure why it happened, but if anyone can help me try to understand that happened, here is the log file to give a glimpse of what happened.
