[SR-Users] High number of aborted mysql connections

Hi all, I'm trying to understand why some Kamailio processes become Connor MacLeod and go to live forever causing high # of aborted connections. While watching in time over *SHOW PROCESSLIST*, some 12 kamailio connections in *SLEEP* state, most of them are reused over time (time value gets reset). However, a select few go on to SLEEP forever for as much as the mysql's *wait_timeout* allows them to. Default was 28800 sec, that's how long they lived. If I lower this to say 600 sec, even higher abort rate is observed. I suppose my questions are: 1. Is this normal to have so many SLEEPing connections? 2. What is the recommended MySQL *wait_timeout* value under Kamailio? 3. Any other suggestions as to why such a high rate of aborted connections? Merci!
