    if this is a critical system and you have support i would advise you to contact F5 support and open a ticket.

     

    if you want to trouble shoot via this place then i would first go to through the trouble shooting SOL about sync issue. it seems that for some reason your systems don't communicate any more.

    the aggressive mode sweeper might indication heavy load / many sessions on the standby node.
