Few Minutes ago I received an alert that one of the collector is disconnected from the MOM. when I check the logs I found following ERROR in logs.
3/28/18 12:00:38.141 PM EDT [ERROR] [Carver data management] [Manager] Uncaught Exception in Enterprise Manager: In thread Carver data management and the message is java.lang.OutOfMemoryError: Java heap space
This error doesn't make sense because this is our new cluster have 16 GB of physical memory in which 12 GB of heap assigned.
This is not the fist time we are getting this problem almost every week. There is no agent connected to this cluster. I build it for our future need.
Here is the Cluster Details.
