DQM process crashing when system running out of Memory

Products

• CA Automic Dollar Universe

Issue/Introduction

The DQM process is killed / crashed by the Operating System while submitting many jobs and running out of Memory (RAM or Swap)

Cause

System running out of memory / pagefile due to the load on the server

 

Environment

Release : 6.x

Component : DOLLAR UNIVERSE

Resolution

In order to workaround the issue, restart manually DQM once it goes offline.

In order to fix the issue, please increase the memory and virtual memory ( Swap or pagefile ) of the server to avoid this from occurring. 

Additionally, I would reduce the number of parallel jobs that can be launched simultaneously on the same server.
