EmployeeAre there any other messages before or after this suspected failover? what type of HA do you have setup? Can you check the other devices logs as well? It's also easier to parse logs using ihealth qkview analyzer. I would upload both BIG-IP device qkviews to ihealth and check the log search feature and look for "failover" or active/standby messages.

We have one suspect log, but we haven't found any documentation that fully matches it.

This could indicate packet loss | network disruption between devices. Error Message: 010c0083:4: No failover status messages received for <timeout> seconds, from device <device> (<IP_address>) (f5.com). Are both of your devices exhibiting the same log messages? Is your HA setup across the network? Directly connected between devices ?
