I have HeroLib installed as part of Hero Rotation.
The memory usage for HeroLib is increasing by 0.03MB every second, when I'm stationary, out of combat and without Hero Rotation displayed (turned off OOC).
It's currently at 30MB and continuing to increase.

Sounds about average for hero lib. Are you running out of memory or something because of 30MB?

WoW automatically cleans the allocated memory used by addons when it reach a certain amount (devs rised the limit again in prepatch). Nothing weird to me

Nowdays most of users have a minimum 8gb RAM, so HeroLib using 30mb along with HeroCache is nothing.

If you find or think about a possible memory leak, open a issue with a detailed explanation of how/whats happening.

Closing this issue for now

Not running out of memory or anything, but surely the memory continuously increasing when the addon isn't doing anything is a sign of something being wrong?? Whatever.

Sure, if it was rocketing its way through tons of memory really quickly and triggering garbage collections really frequently there's a problem. 0.03 MB/s isn't much at all, and it usually tapers off and stops at a certain point anyways.

Just because you don't see it doing anything doesn't mean it isn't running or doing anything. It's constantly running combat checks to see if you're in combat if it should show you anything, for example.
