Issue/Introduction

The Enforce console shows low disk space on a Detection server.
After deleting some dump files the Detection server shows that the disk space utilization has decreased well below the "BoxMonitor.DiskUsageWarning" value.
However, the Enforce console still shows that the Detection server has low disk space.

In this case, the low disk space was not caused by queued incidents.
And a restart of the Detection Server Service did not clear the low disk space warning.

The BoxMonitor log shows the following SEVERE entry a few seconds after 2320 hours daily:

Class: com.vontu.logging.LocalLogWriter
Method: write
Level: SEVERE
Message:  Low disk space. Hard disk space is low. Symantec Data Loss Prevention server disk usage is over 92%.

Resolution

Once the disk space on the Detection server was recovered by deleting the dump files, the console displayed the correct disk utilization the following day.
There is no configuration option to modify the time or frequency of the disk utilization reporting.
