I am getting this error while trying to deploy Drools Business Central using Wildfly. The Error says: Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "jaeger.RemoteReporter-FlushTimer"

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "pool-15-thread-1"

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "mysql-cj-abandoned-connection-cleanup"

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "MSC service thread 1-1"

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "default Accept"

Can anyone help me resolve this issue?

I tried increasing the memory allocation using the below code: JAVA_OPTS="-Xms1024m -Xmx2048m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m"

But this didn't work.

  • "this didn't work" isn't very useful as a problem report. What did happen? What does the memory usage look like in your VM? what troubleshooting have you attempted? (How did you choose those values in the JAVA_OPTS?) – Roddy of the Frozen Peas Jun 03 '23 at 20:02
  • What value did you change them to? Did you confirm they had taken effect by looking at the command line arguments to the process or using jconsole? – Will Tatam Jun 04 '23 at 13:11
