vmware-plugin.out:

2025-05-20T01:45:43.373Z PPDM liveness HEARTBEAT from service vmware-plugin
java.lang.OutOfMemoryError: Java heap space
Dumping heap to /var/log/brs/vmware-plugin/java_pid69079.hprof ...
Heap dump file created [365106841 bytes in 2.321 secs]
Terminating due to java.lang.OutOfMemoryError: Java heap space

The vmware-plugin service ran out of memory.

This is evident from the error message:

java.lang.OutOfMemoryError: Java heap space

The maximum memory the vmware-plugin service can allocate is by default 312MB, as specified in the file /usr/local/brs/lib/vmware-plugin/bin/vmware-plugin.

Also, the garbage collection logs (jvm-gc-vmware-plugin.log) show that the Java process was experiencing allocation failures, leading to a full pause in the garbage collection process:

[2025-05-20T01:45:57.775+0000] GC(59719) Pause Full (Allocation Failure) 219M->219M(223M) 95.545ms
[2025-05-20T01:45:58.067+0000] GC(59722) Pause Full (Allocation Failure) 219M->219M(223M) 94.374ms

These errors and logs indicate that the vmware-plugin service was terminated due to a Java heap space error, causing the service to restart.

To clear the alert in the PPDM UI, remove the java heap dump.

If this was a one-time issue, monitor for future occurrences.

If the service is unresponsive too often, contact Dell Customer Support for further assistance, providing a PPDM log bundle.
