Greetings,
We are migrating our controls network to Alma Linux 9.2 and are now having issues with Pheobus,
namely that it crashes due to "insufficient memory for the Java Runtime Environment to continue".

The text of the message mentions "or process/resource limits reached".
Have you investigated RLIMIT_NPROC?

(although I may be getting confused about OS as you mention both OSX and Windows below)

We are using v4.7.2-SNAPSHOT.  We've done a number of tests, and the summary of results are:

WORKS OK:
SLF7 + openjdk-11.0.17.0.8-2       on VM with 3GB, 3 CPU
SLF7 + openjdk-11.0.17.0.8-2       on VM with 2GB, 2 CPU
Alma 9 + openjdk-11.0.20.0.8-3    on VM with 3GB, 3 CPU displaying on Mac + XQuartz
This one is strange.  It works on a Mac but not on MS Windows.  The only obvious difference seen with 'xdpyinfo' is that XQuartz
on the Mac has a WINDOWS-DRI extension which Cygwin-X does not have.

DOESN'T WORK:  fails with "There is insufficient memory for the Java Runtime Environment to continue."
Alma 9 + openjdk-11.0.20.0.8-3    on VM with 3GB,  3 CPU displaying on Windows+Cygwin-X and on another linux box with x-forwarding
Alma 9 + openjdk-17.0.8.0.7-2     on VM with 3GB,  3 CPU displaying on Windows+Cygwin-X and on another linux box with x-forwarding
Alma 9 + openjdk-11.0.20.0.8-3    on VM with 16GB, 3 CPU displaying on Windows+Cygwin-X

A screenshot of what happens immediately before Pheobus crashes after attempting to open a 3rd bob file:

Is there some configuration that we need that we are not providing?  Our java options are:

I know little about java, so I don't know how severe the SEVERE warnings are.

Attached is the logging.properties file.

Many thanks,
