[jitsi-users] Jitsi high cpu usage and stalling on SIP calls with Cisco CUCM


#1

Hi,
I was using Jitsi with our Cisco CUCM system and recently i found that
after a while all the calls lead to high cpu usage by the java process
after a while and the audio was interrupted.

The java process started to use 400-800% cpu on a quad core i7 system.
Initially it comes in bursts of about 1 second repeating after a few
seconds, each peak being longer. During these peaks the audio was
interrupted. After a while there was no audio and the cpu usage fixed
itself at ~750%, i suppose grabbing every cpu resource available.

Environment is:

Debian GNU/Linux stretch/sid 64 bit (testing)
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

Jitsi 2.8.5426-1 (but i had this issue for some time).

Intel(R) Core(TM) i7-4800MQ CPU
