[OpenSER-Users] TLS Registrations start dropping?

Information on TLS and OpenSER with this specific issues seems to be scarce. I have 2 different setups. One with about 130 registrations, one with about 250. Both with SSLv23 turned on, and TLS is enabled in the phones. What's odd is after some unknown amount of time, phones start dropping like files and fail to re-register. (Our registration timer is set at 60 seconds to aid in failover). What's interesting is it appears that the SSL handshake completely fails when this starts to happen. The requests from the phones are smaller in size (733 bytes about 970 for a good one). Suspicion would normally lie with the phones. They're obviously not doing something right! Here's the kicker. If I fail over to another OpenSER proxy (we move the IP over, use the same certs, etc...) everyone comes back up, and everything is happy for hours, maybe a day, maybe a week, and then it all starts going downhill again. I've increased the number of OpenSER children, I've played with the tcp_persistent_flag. None of these things have stopped the madness. Anyone have any ideas or thoughts? --Chris
