Thanks Bill the #erase worked. The layer 2 has been updating steadily since
doing that.
Due to the nature of the business I work for I am unable to send the logs. Is
there something I could look for in the logs that might help you troubleshoot
the issue? (I made a copy before #eraseing)
Please look for the word "Traceback" and a bunch of lines like the
following (double-spaced).

There is no customer proprietary information in this traceback, but it
pinpoints the error. (This "scanRemoteIf" bug is already fixed for 5.4b4.)
I did notice the problem seems to occur when I add one of our 3750 to
intermapper. There is an SNMP bug with the current and previous versions of
IOS that run on the 3750's. (Cisco bug CSCtg62793)
https://supportforums.cisco.com/thread/2036040
The bug could be unrelated but thought I would mention it.
I'm glad you brought this up, because it may explain one device issue
that has been reported.
I've noticed on some maps the layer 2 is not resolving the all the MAC address
an IP. Is there something I could look for to resolve this?
To resolve MAC's to IP on a remote network, there needs to be an SNMP
device on at least one L2-enabled map that can be polled for
ipNetToMediaTable. In addition, the device (or devices) polled for
ipNetToMediaTable has to talk to the unresolved MAC so there is an IP ->
MAC entry in its ARP table. If you put a router on the L2 map, it will
be polled for its ARP table. You can force more devices into the
router's ARP table by running a ping sweep of the subnet using the Scan
Network... button.
For the local network, the InterMapper server's ARP table is accessible
on Mac OS X. Starting with 5.4b4, it is also available on Windows.
