When trying to run the JVMD agent against a target Java version 1.6.0_29, it is found that the deployed JVMD agent is 
intermittently causing the target JVM of the target server to crash.

An hs_err_pid<PID>.log file will be produced, which will show the JVM crashing on a native JVMD agent library :
