On MDM v126.96.36.199 / FW 188.8.131.52, while running batch coherence cluster in members are being ejected from cluster. The problem is encountered with MDM batch coherence cluster with 6 identical virtual machines retaining communications with each other.
This has resulted in a severe rash of batch aborts that have required us to continually restart our TPW (threadpoolworker) over the past 4 days. The VMs have been rebooted the a couple times.
Actions to mitigate possibility of high CPU and memory utilization included reducing the number of TPWs running on each server and number of threads reduced on largest batch job. None of these changes have corrected the problem.
