a node fails and restarts in a cluster

[es70 <es...@gmail.com>]

I have a cluster of 2 ignite (version 2.6) nodes with enabled persistence (at
the time of writing running on my windows machine for test puposes) and
third  node (not in the cluster) which I use to run my app in the thick
client mode. The app creates a cache (CacheMode.REPLICATED,
CacheAtomicityMode.TRANSACTIONAL, CacheWriteSynchronizationMode.FULL_SYNC)
to store messages being exchanged between the integrated systems. 

I start the messages exchange and brings down one of the nodes in the
cluster (the app shows some execptions but continue working). 

I have two scenarios for the downed node to get it back on line 
1. I start the downed node immediatelly after downing it. 
2. I start the downed node some time (half an hour or so) after downing it. 

in the case #1 the node gets back to the cluster and starts working 
in the case #2 the node refuses to get back to the cluster and I have to
restart the other node to get the cluster to the active state again. Besides
I cannot connect to the cluster (with one node left) with my app and
ignitevisorcmd.bat before the restart all the nodes
