Concourse memory leak


#1

Hello Colleagues,

Concourse web nodes are getting repeatedly loaded high(memory).
What are all the possible causes?

Could you post the memory usage graph that shows that it is a leak ?

Unfortunately we dont have dashboard for concourse web. I have found from bosh --vitals. All the the time memory is ~90+.
I wanted to understand what are all the possible causes for this situation. What are all the checks i can do from my side to understand what is causing the problem.??

The fact that memory is at 90% doesn’t mean it is a leak! To say it is a leak, you need to observe it over time.

I think first you have to extinguish the fire. Add more memory.

Then you have to setup metrics collection and monitoring. You NEED this to operate Concourse. See https://concourse-ci.org/metrics.html. Then you can troubleshoot and be proactive, instead of being reactive. There is no magic answer that can reduce your memory consumption.
