------------------------------------------------------------------

We have been getting Java Heap Space Out of Memory Error in CloudStack Management Server frequently
with CS release 4.5.2 and 4.6.0

We have providing load to CloudStack Management Server with below screnarios.

01. VM creation, VM Deletion, Volume Creation, Volume Deletion via Selenuim automated script.
The cloudstack management server runs for a day and later mangment service gets down due to
Java Heap Space Out of Memory Error.

02. External API calls to Cloudstack Management Server for VM creation, VM Deletion, Volume
Creation, Volume Deletion. The cloudstack management server runs for few hours and later mangment
service gets down due to Java Heap Space Out of Memory Error.

03. API Calls via jar file for VM creation, VM Deletion, VM Rename, Volume Creation, Volume
Deletion. The cloudstack management server runs for few hours and later mangment service gets
down due to Java Heap Space Out of Memory Error.

We have enclosed hprof dump file that was generated during Java Heap Space Out of Memory Error.
Also please see below log from cloudstack management server
