Hello everyone,
I have yet another issue with my cluster. I have seen this issue in other forum entries,
however I am unable to locate the definite answer for it's cause.
I have a cluster which consists of 6 nodes. I have implemented fail-over and session
replication within the cluster. My problem is, that when specific nodes in my cluster are
stopped, their session information is not accurate when fail-over occurs.
I have investigated into each nodes logs and I have discovered that not all of my nodes
have this problem.
Here is the entry from a node which does have the problem, as I called the shutdown.

I do not understand why one node is not able to be removed and the other is. My two
configurations are the same. "DistributedReplicantManager" is able to remove one
node, and not the other, what causes this?
Could anyone please advise as to what my problem may be?
Thank you in advance.
