Yes - but they are needed to compile and query the module,
which is the best way to find out exactly what it happening,
and how to fix it.

That's not a problem - it's easy enough to whip up a dummy set of data
to work with. (Though the use of 'LogWrapper' routines didn't help either.)
I've finally managed to construct a working example, and reproduced
the problem. The fix is also very straightforward.
Just add the following code snippet:
case 13:
case 14:
netsnmp_set_request_error(reqinfo, request,
SNMP_NOSUCHOBJECT);
break;
to the
case MODE_GET:
switch(table_info->colnum) {
block.
That is sufficient to let the table helper know that these MIB objects
are missing, and that GETNEXT requests should move on to the
next column.
You'll probably also need a similar check in the SET_RESERVE1
block, to reject SET requests for these missing objects.
