Hello,
I couldn't spot any error message in the log file that you attached,
have you taken it when you encountered the problem?
Anyhow, I am not familiar with the implementation of the
event_route[network:msg], but the shm info indicates the leak to be
related to avp, so I pushed a patch to destroy the nio_msg_avp avp after
event route execution. Can you try with git master branch and see if
works ok?
Cheers,
Daniel
