We've been running into problems with running out of PermGen memory using TeamCity 9.0.1. We've managed to solve most of them using settings recommend in the docs, but we've noticed the Garbage Collector is still not being initiated to free space until the PermGen memory is already maxed out. Is there a recommended way to decrease the threshold so the garbage collector will kick in around 85%? The lost productivity of having to recover the entire service is much worse than any performance hit we'd take from running the gc more often. I'm posting a screenshot of our diagnostics to help make the situation more clear.
