You are getting the warnings because some of the MIBs in your installation 
are not parsing cleanly.  check_snmp will load all the mibs in the path in 
order to translate ifnumber.0 into .1.3.6.1.2.1.2.1.0.  If there are 
errors reading the mibs, there is error on stderr, hence the warning.

If you can run check_snmp with the explicit OID, then you can add "-m : " 
switch which essentially creates an empty path list to search for mibs.

With no mibs being read - you shouldn't have any parsing issue and 
check_snmp will run a bit faster as well.
