I upgraded the ips module ASA-SSM-20 on the ASA from 5.x to 6.0.3 lately. The ASA are setup as active/standby. i upgraded both modules successfully on each ASA. After the upgrade, i notice the ASA failover to the other partner about 10 times for the past day, particularly when traffic was high. Before the upgrade, i don't have this problem. Anyone run into this problem before, and any idea? thanks.
