BIG-IP AFM(all modules)

Known Affected Versions:
14.1.0,,,,,,, 14.1.2, 15.0.0, 15.0.1

Opened: May 12, 2019
Severity: 3-Major


Monpd allocates excessive memory on multi-blade devices, and in some cases the kernel may kill monpd. The following log signature may be encountered in /var/log/kern.log: err kernel: : [1537424.588160] Out of memory: Kill process 28371 (monpd) score 117 or sacrifice child


Large fluctuations in host memory usage, occasionally leading to OOM events.


This can occur in a multi-blade BIG-IP environment when you are displaying pages that query for network_log data, for example Bot Defense requests in the event log, or realtime AVR data.
