[rancid] UBR error

[Rob Wynne]

We recently brought a new customer online and configured our RANCID
installation for their equipment.  One of the CMTS devices is not
reporting properly, and I'm not sure how to troubleshoot it.

Here's the info on the device:

IOS (tm) 7200 Software (UBR7200-IK8S-M), Version 12.2(15)BC2f, RELEASE
SOFTWARE (fc1)
cisco uBR7246VXR (NPE-G1) processor (revision B) with 983040K/65536K
bytes of memory.
Processor board ID CAT09080ETY
SB-1 CPU at 700Mhz, Implementation 1, Rev 0.2, 512KB L2 Cache
6 slot VXR midplane, Version 2.
System image file is "disk2:ubr7200-ik8s-mz.122-15.BC2f.bin"

And here's the error from the rancid log:

Trying to get all of the configs.
cmts.xxxxxxx.com: missed cmd(s): write term,show running-config
cmts.xxxxxxx.com: End of run not found
Error: TIMEOUT reached
=====================================
Getting missed routers: round 1.
cmts.xxxxxxx.com: missed cmd(s): write term,show running-config
cmts.xxxxxxx.com: End of run not found
Error: TIMEOUT reached
...etc...

If i clogin to the box and do a write term or show running-config, it
gives me the output I expect.    They have another cmts which is
reporting fine, though it's running a different version of the IOS:

IOS (tm) 7200 Software (UBR7200-IK9S-M), Experimental Version 12.3
cisco uBR7246VXR (NPE-G1) processor (revision A) with 983040K/65536K
bytes of memory.
Processor board ID SCA061600NC
SB-1 CPU at 700MHz, Implementation 1, Rev 0.2, 512KB L2 Cache
6 slot VXR midplane, Version 2.0
System image file is "disk2:ubr7200-ik9s-mz.123-9a.BC7.bin"

Any help in how to isolate this would be appreciated.
