Re: [Cs-studio-users] Filling Memory when observing PVs

[Kasemir, K. <kas...@or...>]

Hi:

Thanks to Gabriele for the good description of general GC behavior.

With either OpenJDK or the Oracle JDK, have you seen it crash with OutOfMemoryError?
Or is it simply using memory towards the permitted limit?

I am aware of a perm gen memory issue with Jython (https://github.com/ControlSystemStudio/cs-studio/issues/256, http://bugs.jython.org/issue1746).
The CSS ticket is about the Scan Server, but it may be the same for Jython scripts inside BOY.
The manifestation would be a pretty obvious java.lang.OutOfMemoryError: Permgen space.

Thanks,
Kay
