Hi Amit,

if the real server unexpectly resets the connection, but is not yet marked as down by the health monitor, then you could try to catch this event using the LB::failed event.

when CLIENT_ACCEPTED {
    set retries 0
}

when LB_FAILED {
    if { $retries < [active_members [LB::server pool]] } {

        incr retries
    }
}
