Without a way to reproduce, it is difficult to deal with the problem.

Hopefully, this will allow you to do so: https://github.com/pbella/

This turned out to be tricky to provide a repo case for since I'm not sure
exactly what is triggering it so I reproduced the type of work I'm throwing
at the VM (it's a bulk parser/loader) where there's lots of continuous
allocation going on with the occasional saving of a result to generate lots
of garbage.  This should run in 5-10 minutes depending on the speed of your

The main caveat is that I'm only able to get this example to reliably
reproduce with the included VM with the commented VM parameters applied.
So I'm not sure if this is an issue only with this particular VM/parameter
combination or if it's just generally a difficult to reproduce issue.
