Hello!

Regarding PME problems.
OOM will cause this. High GC could cause this under some circumstances.
High CPU or Disk usage should not cause this. Network inavailability (such
as closed communication port) could also cause it.

But the prime cause is programming errors. Either those are errors on
Apache Ignite side (caused by some strange circumstances since all normal
cases should be normally tested), or they are in your code.

Such as deadlocks. If you have deadlocks in your code exposed to Apache
Ignite, or you are manage to lock up Apache Ignite in other ways
(listeners, invokes and continuous queries are notorious for that, since
there are limitations on operations you can use from within them), you can
catch infinite PME very easily.

However, it's hard to say without reviewing logs and thread dumps./
