[StarCluster] StarCluster Digest, Vol 67, Issue 1

[Pere Toran]

Hi,

This is also happening to me sometimes. My clusters are of 25 servers at
most and sometimes it takes minutes (not 40 but 5 or 6 minutes) to remove
each node and it hangs at the same point.
I assume it's a network problem?

Regards,
Pere
