James Peach commented on TS-3554:
---------------------------------
FWIW, I looked at this (or something similar) some time ago I wasn't able to
prove there was a leak. However when you get large numbers of certificates,
what can happen is that the background certificate stores are released slower
than new ones are created. Nothing is leaked, but memory accumulates.
> ATS memory leak reloading ssl_multicert.config with many ssl cert configs

> Key: TS-3554
> URL: https://issues.apache.org/jira/browse/TS-3554
> Project: Traffic Server
> Issue Type: Bug
> Components: Configuration, Core, SSL
> Reporter: Steven Feltner
> Assignee: Susan Hinrichs
> Fix For: 6.0.0
>
>
> ATS will consume all available memory on a server with 128GB of RAM.
> @shinrich suspects it may be due to CertLookup table not being freed on a
> config reload.
> Our current process:
> - New cert comes in
> - ssl_multicert.config and remap.config updated
> - traffic_line -x
> This reload could occur as often as every 3 mins with 5000+ certs configured.
