Randomly IST Received Failed

protosschrisprotosschris EntrantCurrent User Role Beginner
Hi,

I have a Six-Node Percona Xtradb Cluter,
I'm facing a really strange problem, "Randomly IST Received Failed" problem that only happend with one node.

I certainly doubt that may be a firewall problem.
But I try to turn off iptables (both mall-db-cluster-005 & mall-db-cluster-006) , and with no luck.
The problem is still remain.

So any idea will be helpful, thanks.
