Summary: Offiline RTP Proxy causes system freeze
Initial Comment:
I have a setup running multiple RTP Proxy instances, when multiple rtp proxies fail, CPU utilisation approaches 100%, this does not usually happen with 1 or 2 failures, but when 4+ fail (this can even be 4 instances on an 8 core/instance machine), the issues arrise.
The severity of this event happening has caused the system to stop responding for short periods, observations notice intermittent periods of no logging information and substantial packet drops (due to high CPU usage).
Once RTP Proxy instances that have failed come back online, CPU utilisation drops right down and everything functions as expected.

Hello!
My assumption is that OpenSIPS is trying to probe the other RTPProxy
servers without any success. That's probably why the CPU goes that high.
How many OpenSIPS processes are you using? Are you using the
rtpproxy_disable_tout [1] parameter? If yes, what value are you setting?
Have you tried to permanently disable via MI commands [2 ]the RTPProxy
servers that failed?
