Problem: Moab outputs show nodes as Idle, with zero processors ("0/0").
Solution: This frequently occurs when sites add new nodes. Most likely the number of nodes and sockets has exceeded what the current license allows.
Run "mdiag -l" and "mdiag -S" to check for errors. Normally you'll see this message at the bottom of "mdiag -S" when exceeding the license limit:
Message[WARNING] too many nodes detected for current licensed limit
Contact Sales and/or your contract rep about an updated license file.
