> Found the following problems in the monitor when trying to bring up 120 nodes:
> 1. A segmentation violation occurred during the Integration phase, when the new monitor is establishing the socket communication paths between itself and the existing monitors.
> 2. A second segmentation violation was due to a buffer overwrite during the Joining (revive) phase.
> 3. One of the monitor would remain in the Joining state and never come out of it.
> 4. Stderr buffer overwrite in CRedirectStderr::handleOutput()
