Issue with Elasticsearch

scottalanmiller

Had you set the heap size already? Or are you looking at increasing it now?

Ambarishrh

Just increased, to 2 gb just to check and so far its been running well. Will keep monitoring this.

Ambarishrh

It failed again!

scottalanmiller

What does SAR show?

Ambarishrh

Is it sar -v?

scottalanmiller

Output of sar and sar -r would be best.

how many vCPU is that? It's definitely very busy, but not crazy.

(4 CPU)

Ambarishrh

It has ActiveCollab used which uses Elasticsearch, used by around 50 users

scottalanmiller

At what time mark is the crash happening?

Ambarishrh

It used to be around 30 minutes after the service is started, not sure if changing the heap size made any difference but the last failure was after an hour later. May be because the usage is less, not sure

scottalanmiller

I mean where in the SAR time listing would I see what it looked like at crash time.

Ambarishrh

That would be around 9

Odd, I don't see memory freeing up after the crash.

This doesn't fix the problem, but you could use something like monit or supervisord to start it up again after it quits.

Ambarishrh

@johnhooks monit looks promising. Is there any specific option by which I can monitor the Elasticsearch failing?

It's been a while since I used it, but I think it uses /var/log/monit.log and will track errors. If not, you can set the log in the config file under the set logfile line.

Ambarishrh

Seems like its java which is causing the issue. I have cloudlinux on the server, and that also might be an issue as it jails the user to use resources. Just removed elasticsearch user from cagefs to see if this solves the issue. Then i need to find out the right resources that needs to be allocated and bring back to caged setup. Waiting to see if it crashes again

Solved Issue with Elasticsearch
