Investigate memory leak in precached
Closed, ResolvedPublic


We just had another minor outage of ores-web-03. It looks like the precached utility was using 3.1GB of memory!

Event Timeline

Happened again just a moment ago. It looks like the same story with precached.

I noted in meeting that I suspect that there's something going on with metrics collection.

Halfak triaged this task as High priority.

I worked out that there was a datastructure that would grow slowly over time. I just submitted that should address the issue.
