Hello,
isn't the maximum JVM Memory usually set as the max heap by default? Screenshot attached with our current configuration, assuming that XMX is the heap size.

If you have configured your heap with the CATALINA_OPTS in setenv. Make sure that the JVM configuration (JVM_MAXIMUM_MEMORY) is not the same value as the max heap configured in CATALINA_OPTS.
Best regards
