Title: netxmsd Killed, Ran Out of Memory?
Post by: zapp25 on February 12, 2020, 05:51:13 PM
Every few days netxmsd dies due to it being out of memory. I'll get an error on my console stating "Out of memory: Kill process xxxx (netxmsd) score 94x or sacrifice child" with the following notification that the process has been killed. Anyone seeing this type of behavior? I'm running 3.1.343 on a VM with 8 vCPUs and 32GB of memory on Ubuntu 18.04.4 (installed from repo). My only thought is I could be flooding the server with several thousand syslog messages.

How many objects do you have in the systems? What are queue sizes?
Show output of:
* nxadm -c 'sh st'
* nxadm -c 'sh q'

23,758 Objects.

Just had to restart the daemon so it's still populating.

4 DB writer queues are currently set.
