Issue/Introduction

Having an issue with APMIA Infrastructure Agent.

.dmp(core.20200807.171828.2280.0001.dmp) files.

A high number of files are being created under this location (CA APM/APMIA ) and the total size of all .dmp files is going up to 50 GB.


Cause

Core Dump files are being created due to "out of memory" errors. Can see this from the Log:
