Issue/Introduction

Description:

Since upgrading to IM 2.3 the DCs are terminating and the following message is seen on the console: "Out of memory: Killed process [x], UID 0, (java)"

Solution:

To resolve this issue do the following .....

1. cat /proc/meminfo and make note of "MemTotal" value
   
   
2. cat /opt/IMDataCollector/apache-karaf-2.3.0/bin/setenv and make note of IM_MAX_MEM value
   
   
3. If the values from #1 and #2 are equal than this is the reason for the "out of memory" condition as java will consume all the memory on the box
   
   
4. Stop the data collector process with the following command: /etc/init.d/dcmd stop
   
   
5. Change the IM_MAX_MEM value in /opt/IMDataCollector/apache-karaf-2.3.0/bin/setenv so that it equals half the total of "MemTotal" noted in step #1
   
   
6. Start the data collector with the following command: /etc/init.d/dcmd start

This should resolve the out of memory condition
