I have written a test harness application that demonstrates the issue. When there are 3 members in the group, 2 on 1 machine and the third on a second machine not all members of the group receive a viewAccepted method call everytime a network outage occurs or after a network outage has been recovered from. I am doing all my testing on Windows XP.

Receiving the viewAccepted method after a network outage or after recovering from a network outage is vital for all members to be able to keep track of which members are still present in the group.

I have created a thread on the forum regarding this issue:

Although I have only seen the error reported at the start of that thread once so it may be a red herring. It may be necessary to break the network connection between the 2 machines in this test 3/4 times as it sometimes works.

If you need anymore information on how to recreate this issue then please let me know and I will try to assist.
