When processing 'empty' reports (that is, reports containing no data), monpd has a memory leak.


Memory is gradually exhausted.


This might happen when no traffic or data runs for more than 5 minutes through a module that reports to AVR, and therefore no data should be presented by AVR.


To prevent this issue, monitor memory usage and restart monpd prior to the system running out of memory.

Fix Information

Previously, a memory leak in the monpd daemon occurred in some situations. It no longer occurs.
