[rancid] Issue with nx-os after switch upgrades

[John Livingston]

I have a set of MDS switches that yesterday were upgraded from SAN-OS 3.3 to NX-OS 5.2 and now the nxrancid script is failing with an "end of run not found" error message as shown below:

	ibmbc1-fc2: missed cmd(s): show running-config
	ibmbc1-fc2: missed cmd(s): show running-config
	ibmbc1-fc2: End of run not found
	ibmbc1-fc2: End of run not found
	ibmbc1-fc2: clean: 0, end: 0
	!PROC_LOGS:                                   ^

Any recommendations or advise on how to fix this?  I have another 10 or so switches to go this weekend and don't want to lose backups on these.  Currently running version 2.3.8 of rancid and using the stock nxrancid script.

Thanks,
John
