In high-loss networks, an assert based on a constant value for the retransmit message queue size could have caused a some nodes to receive SIGABRT signals, and therefore terminate. This constant value has been increased to correspond to the maximum number of entries, thus resolving the issue.
Description of problem:
The queue length is not long enough for really high loss networks resulting in sigabort. Instead of 512 entries, it should be the max entries allowed which is 16384 entries.
Version-Release number of selected component (if applicable):
openais-0.80.6
How reproducible:
100%
Steps to Reproduce:
1. create 95% loss in multicast packets
2. start 8 node cpgverify operation
3. kill 1 node
Actual results:
sigabort of some nodes
Expected results:
no sigabort
