iDash Client Out of Java Memory

Issue/Introduction

 We run a daily job to create an iDash latency report on the iDash Client. The report used to work fine for months, but suddenly started to fail with errors :

Exception in thread "PoolCleaner[29855319:1451473016745]" java.lang.OutOfMemoryError: Java heap space 

com.ca.idash.core.exception.IdashException: java.lang.OutOfMemoryError:Java heap space 

java.lang.OutOfMemoryError:Java heap space

com.ca.idash.core.exception.IdashException: java.lang.OutOfMemoryError:Java heap space 

However, when the same command is run directly on the iDash servers the report is generated without any issues. 

Environment

IDash WA

Cause

Problem due to lack of Java memory on the iDash Client 

Resolution

The solution is to increase the Java memory on the client by passing “-Xms2048m –Xmx2048m” in the command line.

  Example :

/opt/idash/bin/idgencsv -Xms2048m -Xmx2048m -f /tmp/graham.csv –t latency.report –i HP1 –v

 

These options are added at command line when you execute the "idgencsv" command
