Issue/Introduction

Disk full errors occur daily on a DLP Discover server that's running a scan. 
Checking the server, large .hprof files are being generated in a temp directory. 

 

 

Environment

Symantec Data Loss Prevention 15.7 MP3

Cause

.hprof files are full memory dumps for java. They are not enabled by default.

Resolution

  1. If the full memory dump is not needed, turn it off.
    In the Enforce Console, navigate to System > Servers and Detectors > select the detection server > Server Settings.
    Remove '-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=xxxxx' from BoxMonitor.FileReaderMemory

    Example:
    BoxMonitor.FileReaderMemory = -Xrs -Xms3379M -Xmx11264M -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=F:\Temp

    Remove the memory dump setting to look like the following:
    BoxMonitor.FileReaderMemory = -Xrs -Xms3379M -Xmx11264M 

  2.  Restart services on the Detection server.
