Zhao Yongming commented on TS-3181:
-----------------------------------
for example, we should try to filter out these issues with cluster enabled:
{code}
[Nov 7 15:28:21.428] Manager {0x7f277bfff700} NOTE:
[ClusterCom::drainIncomingChannel] Unexpected message on cluster port.
Possibly an attack
[Nov 7 15:28:57.501] Manager {0x7f277bfff700} NOTE:
[ClusterCom::drainIncomingChannel] Unexpected message on cluster port.
Possibly an attack
[Nov 7 15:34:09.624] Manager {0x7f277bfff700} NOTE:
[ClusterCom::drainIncomingChannel] Unexpected message on cluster port.
Possibly an attack
[Nov 7 15:38:36.235] Manager {0x7f277bfff700} NOTE:
[ClusterCom::drainIncomingChannel] Unexpected message on cluster port.
Possibly an attack
[Nov 7 15:39:45.596] Manager {0x7f277bfff700} NOTE:
[ClusterCom::drainIncomingChannel] Unexpected message on cluster port.

{code}
> manager ports should only do local network interaction
