[SR-Users] OOM Errors

[Phil Lavin]

Thanks, Daniel.

Kamailio has been restarted now so there’s not much of any use in the pkg memory output.

I’m going to add some monitoring/graphing on this and see if there’s an upward trend in usage.

Hello,

it seems that the pkg is out of free space, not shm. You can check it with:

kamcmd pkg.stats

and look for the same pid that printed the log messages.

To troubleshoot, it is good to print the pkg summary, see:

  - https://www.kamailio.org/docs/modules/stable/modules/corex.html#corex.rpc.pkg_summary

Then get the log messages from syslog printed by the command and send them over here.

Cheers,
Daniel

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 at 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
