Hi all,

Kamailio stopped performing some functions earlier today, citing OOM errors. An excerpt from the log is below.

SHM usage, at the time, looked fine. Also see below for that output.

A restart of Kamailio resolved the issue. Is this SHM related or OS memory manager related?

root@ua-proxy-01:~# kamctl stats shmem

shmem:fragments = 910

shmem:free_size = 104131224

shmem:max_used_size =  51590800

shmem:real_used_size = 30086504

shmem:total_size = 134217728

shmem:used_size =  19558800
