HA Sync issue on Active-Active Cluster

Hello there! 

This log caught my attention:

err mcpd[9977]: 0107102b:3: Master Key decrypt failure - decrypt failure - final(not sure if this is related)

in a BIG-IP HA cluster, peers usually sync their master key when you create the device group for the first time. 

You can run the following command on both peers and see if they match: 

f5mku -K

If they don't, which would be wierd, you should probably fix this before you attempt to perform a config sync again. 

f5mku -r <key> (I'd take the one from current active unit) 

Other than that, you might try and restart TMM

bigstart restart tmm
