Hey everyone.
Really looking to see if anyone has experienced anything similar here. We updated our FTD 1140s to 7.6.4 about 2 months ago and have started seeing High Data Plane memory usage. Recently this has began to cause these Firewalls to crash and manually failover then reboot to bring them back online.
We have already removed all stale Anyconnect packages, due to the related bug, but still experience the high memory usage. Before the upgrade our baseline usage was about 75%, after the upgrade we are regularly around 82-85%. Nothing has changed in our network other than the upgrade to 7.6.4.
Is anyone experiencing anything similar?
