We've recently upgraded AEM from 6.5.5 to 6.5.7 (didn't install 6.5.6) - running on Ubuntu 18.04.5, Java 11.
We have been pretty consistent the last 8-9 months after making some performance adjustments in migrating from 6.3 windows to 6.5 Unbuntu. Rarely having to restart. However, since we've upgraded from SP 6.5.5 to 6.5.7 (we bipassed 6.5.6 - which SHOULDN'T matter), we've noticed really poor performance, author instance needing restarts nearly every 2-3 days and publish instances 5-6 days because of becoming unresponsive. No heap dumps or OutOfMemory exceptions.
I'm just wondering if anybody else might know of any obvious reasons this could be happening before I bog myself down in a sea of heapdumps and threaddumps.

@sdouglasmc we also got the same package from Adobe, it resolved our issue.
Notes from adobe:
Checking the thread dumps and further researching internally, It seems you are running into a known issue(CQ-4312194) with SP7 where numerous threads get blocked due to a Timer with the Component Registry (org.apache.felix.scr.impl.ComponentRegistry). This causes the instance to become unresponsive.
@sdouglasmc is there any resolution or solution on this issue? we are also facing the same issue in our Prod environment.

I would recommend, It would be better if you check with Adobe by raising a ticket rather than getting a package from me and trying as this package is not open-source yet.
That being said, someone mentioned in the comments
"For those who haven't updated to 6.5.7 yet, Adobe has a new SP7 installation package with Hotfix-CQ-4312194-FELIX-6252 included in it. Makes upgrade faster and more stable. This is not publicly available (yet) but you can probably ask for it in a ticket."
