Continuously seeing [monitor_only mode] cancelling task [165525] due to high resource consumption [heap usage exceeded [257mb >= 550kb]]" messages in my cluster

Hey ,

If you noticed in the jvm.options file, its default display looks like this

## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
##
## -Xms4g
## -Xmx4g

Try setting it like so and restart service.

EDIT: @chirumanem found another post that looks like your issue.
