Firewall rule compilation will fail and following message will appear in /var/log/ltm: Serialization failed: No Blobs available. pktclass-daemon will transit in the failed state and any further firewall rule modifications will be rejected till the corrective action is taken.
Firewall rule compilation will fail and pktclass-daemon will go into failed state causing any further firewall rule update to be ignored till user-initiated corrective action is taken.
For this issue to manifest, following conditions may suffice: i) Presence of multiple scheduled firewall rules (expiring at different intervals). ii) Presence of non scheduled firewall rules. iii) Modify any non scheduled firewall rules in between the time interval of expiry to any 2 scheduled rules.
The aforementioned incorrect behavior has been fixed.
