Symptoms

• The Admin Console is up and running for at least several weeks.

• The Admin Console is not responding (/admin endpoint never finishes loading).

• The log files under /logs/appadmin contain the following error message:

  java.lang.OutOfMemoryError: Java heap space

• DPOD version is 1.0.13.0-1.0.14.0
  Note: DPOD 1.0.15.0 will fix this issue.

Cause

The Admin Console runs out of memory due to a memory leak in one of the libraries of the Java application server.

Resolution

As a temporary workaround, until DPOD 1.0.15.0 is available, you may issue the following commands:

sed -i '\#^jms/MonTierAMQResourceAdapter.KeepAliveTime=#d' /app/appadmin/MonTier-AppAdmin/conf/system.properties
echo "" >> /app/appadmin/MonTier-AppAdmin/conf/system.properties
echo "jms/MonTierAMQResourceAdapter.KeepAliveTime=600s" >> /app/appadmin/MonTier-AppAdmin/conf/system.properties
service MonTier-AppAdmin restart

Once DPOD 1.0.15.0 is available, you may use the following command to remove this workaround:

sed -i '\#^jms/MonTierAMQResourceAdapter.KeepAliveTime=#d' /app/appadmin/MonTier-AppAdmin/conf/system.properties
service MonTier-AppAdmin restart
