Out of memory error

Description

It appears that RocketChat (node) ran out of memory:

Out of memory: Kill process 13832 (node) or sacrifice child
Killed process 13832 (node) total-vm:5157888kB, anon-rss:1237720kB, file-rss:0kB, shmem-rss:0kB
rocketchat.service: Main process exited, code=killed, status=9/KILL

If I am reading this correctly, node was using a massive amount of memory. This is a small installation with under 20 users.

Should a memory leak be suspected?

What are the next steps?

I’m continuing to see gradual increase in memory over time. Is this expected?

Virtual RAM usage continues to climb. Resident seems fairly stable. Here is a chart, spanning approx. 20 days:

Resident memory usage is stable but virtual memory is still going up.

It’s starting to reach the critical stage. Swap is over 90% used.

There has to be a memory leak.
