HA testing: node up brings down all Trafodion nodes

After rebooting a node, node up brought down all trafodion nodes. This might be related to bug 1411520. Details are as follows:

===============================================
sea-dev7 cluster: 5 node cluster (without sea-dev8)

idle system
rebooted sea-dev9, nid 1

Trafodion stayed up and was usable/stable

<waited about 30 minutes to make sure node sea-dev9 had completed rebooting>

sqshell up sea-dev9
[$Z000LKJ] %up sea-dev9
[$Z000LKJ] 01/16/2015-11:40:28 - Node sea-dev9 is merging to existing cluster.
[$Z000LKJ] 01/16/2015-11:40:30 - Node sea-dev9 join phase starting.

all Trafodion nodes came down at this point
