Last updated on MAY 12, 2016

Applies to:

Oracle Utilities Mobile Workforce Management - Version 2.0 and later
Oracle Real-Time Scheduler - Version 2.1.0 and later
Oracle Utilities Framework - Version 4.1.0 and later
Information in this document applies to any platform.

Goal

Approximately 2 times a month, depending on the user requests, the system crashes in an out of memory situation.

The heapdump captured on outofmemory shows this class consuming most memory:  com.splwg.mwm.support.scheduler.process.SchedulerLifecycleManager

This is occurring on an IBM JDK, and IBM support has suggested  that 'com/splwg/base/support/scripting/PreparedXQueryCache' is leaking/consuming >50% memory.
