DevTest Registry throwing error "java.lang.OutOfMemoryError: GC overhead limit exceeded"

Products

• CA Application Test
• CA Continuous Application Insight (PathFinder)
• Service Virtualization

Issue/Introduction

have upgraded Devtest and we 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/Lisaxx.x.x 
-Dcom.sun.management.jmxremote.port=4444 
-Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.authenticate=false 

Had not observed this behavior in several days after the above entries under vmoptions but after upgrading it started throwing OOM error again. 

Environment

All supported DevTest releases.

Cause

Needed to increase memory due to the extra load processing.

Resolution

Increase heap size on Registry to

-Xmx6g
