Issue:
We have upgraded Devtest version to 10.2.4 and we have observed Registry going out of Memory again.

Also find the following entries under RegistryService.vmoptions 

-Xmx4096m 
-XX:+UseG1GC 
-XX:MaxGCPauseMillis=200 
-XX:ParallelGCThreads=20 
-XX:ConcGCThreads=5 
-XX:InitiatingHeapOccupancyPercent=70 
-XX:+PrintGCDetails 
-XX:+PrintGCTimeStamps 
-Dlisa.tmpdir=/apps/logs/Lisa10.2.4 
-Dcom.sun.management.jmxremote.port=4444 
-Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.authenticate=false 

We haven't observed this behavior in several days after the above entries under vmoptions but after upgrading to 10.2.4 it started throwing OOM error again. 

Please suggest if there are any tweaking needed in current setup.
Environment:
DevTest 10.2.4
Cause:
Needed to increase memory due to the extra load processing.
Resolution:
Increase heap size on Registry to

-Xmx6g
