Bogdan,I no longer get crashes. However the opensips process hangs pretty badly while the DB operations are going on. I've tried to rewrite my queries to do more small queries rather than longer slow ones.
So what I'm doing, I'm using sipp performing calls at 30CPS lasting 10 seconds (to generate a lot of call records). While this is running, I run my rating script, which gathers unique callid. smashes records together into a cdr record. My database engine is InnoDB and I'm using transactions. I'm not actually getting to a commit in any of this. So while my script is running. I see on the UAS side of sipp, it stops receiving calls, and starts performing retransmissions. I've verified with tshark that packets are hitting opensips, but not getting a reply. I have 20 children running. Am I doing something wrong?
