Still experiencing this on 6000.0.61f1 LTS. Issue is not resolved for us, and issue was introduced when we updated to the security patch.

Issue says this is Fixed in 6000.0.59f1. I did the same as others in this thread (Spawnterminator) and updated to latest version, in hope that it was fixed. In my case I updated to 6000.0.60f1 and the issue is still there. Unsure if I should try 6000.0.59f2, as it is a lower version.

We're now seeing a lot of this among our players on 6000.1.17f1, after upgrading due to the security vulnerability issue.

Follow Up...
Ok, I took the risk ( got impatient for a response, sorry), and downloaded 6000.0.59f2 from the download archive, thinking perhaps the fix I'm looking for is actually in 6000.0.59f1 and 6000.0.59f1 was rolled into 6000.0.59f2, before 6000.0.59f1 could be released (because of the recently discovered vulnerability issue, hence no release notes.
This is on the download archive:
https://unity.com/releases/editor/whats-new/6000.0.59f2#installs
There is no entry for:
https://unity.com/releases/editor/whats-new/6000.0.59f1#installs
So I can't read the release notes, and I can't find any release info about this version online anywhere.
Anyway, downloaded 6000.0.59f2, ran my game, and no Memory leak warnings. Or any other warnings for that matter. :-)
Thanks for resolving this issue
Richard
