Information:

Environment

Affects Versions: 3.x

  • Java Agent
  • Instrumentation

 

Symptoms

Problem
Extended Memory dumps take a long time on IBM JVMs.
This is particularly problematic when running on AIX OS.

Solution

Resolution
At this time, there is no workaround available. dynaTrace is working with IBM to help them resolve this problem.
Be aware of this condition when using Extended Memory dumps with IBM JVMs and particularly when running on AIX.
Note: Be aware that when performing an extended heap dump, the associated application is suspended, so Extended Heap dumps should not be attempted for critical applications when running in these environments.
This problem does not happen with Simple Dumps.
