It means that the mibs files you added do not have the corrent syntax.
The net-snmp package is relatively strict about syntax.

If you don't feel comfortable correcting the syntax, then change the 
invocation of check_snmp


Normally check_snmp will accept either numeric OIDs (e.g. 1.3.6.1.2.1.1.0)  
or textual (e.g. system.0).  When getting textual OIDs, it needs to
convert them to numeric OIDS.  This is where the mib files come into the 
picture.  Bad syntax generates output on stderr and causes a warning.

To bypass this, make sure you are passing only numeric OIDs to check_snmp 
and also add the "-m :" option to check_snmp.

The -m option specifies the mib modules to load.  Just providing a : makes 
it an empty list and none of the mibs are loaded.

This also make the check_snmp plugin run faster.

To convert you textual oids to numeric, try:

snmptranslate -Ib -On textual oid

-- 

-sg
