Last Modified: Nov 07, 2022

Affected Product(s):
BIG-IP AFM(all modules)

Known Affected Versions:

Fixed In:
12.0.0, 11.6.0 HF6, 11.5.3 HF2

Opened: May 15, 2015

Severity: 3-Major


Prior to fix, if AFM rule serialization fails due to OOM condition in pktclass-daemon, it's not identifiable if the failure is due to Out of Memory condition or the Max Blob limit being reached. Both the errors were logged as OOM in /var/log/ltm


Hard to isolate the problem that serialization failed due to max blob limit


AFM rule serialization fails due to max blob limit



Fix Information

With the fix, AFM rule serialization failure due to max blob limit is logged appropriately in /var/log/ltm making it easier to identify the cause of the failure.
