Re: [SR-Users] Kamailio Processes Stop Responding

Peter, The natural question that would arise is whether your SIP worker threads are waiting on any external I/O, such as database queries. When this event occurs, you'll want to take a look at your RecvQ in netstat, e.g. # netstat --inet -n -l | grep 5060 It should be 0 or substantially 0 under normal conditions. If the SIP worker threads are "stuck" waiting on something and unable to cope with the incoming packet load, you'll see the number increase.
