Wily Introscope Manager Heap size issue

Dear experts

We are facing a problem getting error saying OutOfMemoryError thrown by JVM in Wily Introscope 9.1 of Solution Manager 7.1 SP12 (Linux/Oracle)

I am aware that "If a computation requires more heap than can be made available by the automatic storage management system, the Java Virtual Machine throws an OutOfMemoryError."

The required memory for Wily is 1GB per 10 Introscope Agents

The -Xmx and -Xms are set for 13312m each which covers for all Introscope agents in the solution manager 7.1.

We also, deleted some of managed systems that were not used anymore to test whether the size of heap decreases.

However, there were no change in size of heap of Wily Introscope...

Any idea where should check on why the heap size would not decrease and still throws exception of OutOfMemory, when the set fixed size between -Xms and -Xmx are covering the requirements

Any idea or correction would help...

Thank you

    • Mr Yogesh.

      Are you aware of what does, "Custom Metric Host" in Investigator tab of Wily WebView mean?

      What is the difference of agents under this "Custom Metric Host" tab and agents that are shown respectively not under this tab?

      Thank you always
