Memory leak retrieve_conf

[Sanasol]

retrieve_conf eating unlimited ram and doesnt release it after script end.

Using: CentOS 6 (node) + OVZ Debian 7 (vps with freepbx+asterisk)

slab cache growing after each config reload
dentry at slabtop has huge size.

I have ~600 trunks and ringroups
dentry grow +20-30mb per reload. After 15-25 hours i have 25gb used ram, then i need reboot, or OOM kill killing other processes.

How it can be fixed?
Any ideas?

retrieve_conf is a PHP script. There is no way to “release” ram. Considering it’s a PHP process and dies when finished I have no idea where your ram is going but it’s not being retained by the script.

Did you find any solution for this?
I have similar issue.

This is a 5 year old thread. And OP seems to have done a custom intsall.

Please create a new post describing your setup, system details and the issue you are seeing.

Hi!

I dont remember exactly, but we probably just moved to some custom config generator instead of retrieve_conf if I remember correctly.
