Issue/Introduction

During load test, we found that the simulator died this morning;  the Coordinator continues to run , but the simulator crashed.

 

Memory assigned to Simulator in vmoptions file is 

-Xmx1024m

 

Environment

Release : 10.5

Component : CA Service Virtualization

Resolution

We have analyzed the heap dumps and did not find any memory leaks . Since you are running lots of load on Simulator , we have added the following properties and changed memory settings that help resolve the issue


1. suggest that the Max heap memory of the Simulator process be increase from 1024m to 2048m.


a. Edit the file SimulatorService.vmoptions
b. Change the entry -Xmx1024m to -Xmx2048m


2. Add these properties in lisa.properties file . This configuration will ensure that the LisaServerObjects are eligible for garbage collection within 5 seconds from completing its job unlike the default setting which lets these objects linger for 5 minutes.

lisa.net.hardRefs=false
lisa.net.close.idle.ms=5000

Restarted Simulator Service and now we are seeing stability in the environment.
