DistributedTopicTest testFloodSubscription is failling with db2 database

Hi,

DistributedTopicTest.testFloodSubscription is failing in with DB2-97 database.

Test scenario:
1. 3 node in cluster
2. deploy topic on all
3. create connection -> session to each node
4. sequentially subscribe 50 subscribers to topic on each session
... during the 9th subscribe on topic on node 0 this i found in logs:

08:27:59,918 ERROR @Incoming-9,10.16.88.197:60286 [GroupMember] Caught Exception in RequestHandler

It seems like that c1.sess_0_9 wasn't created on node 2 because there is already a channel with this ID. Also failure occurs always when 9th subscription is created.

I'll set priority as major because i'm not sure whether this is test suite problem. Could you look at it please?

Thank you,
