Hmmm....
I've never actually used this flag (and it's a bit difficult to trigger).
But comparing the code in SNMP.xs with the equivalent code in
apps/snmpbulkwalk, I can see a suspicious difference:
SNMP.xs:
if (__oid_cmp(vars->name, vars->name_length,
context->reqbase[pix].last_oid,
context->reqbase[pix].last_len) == 0) {
if (check) {
DBPRT(2, (DBOUT "Error: OID not increasing: %s\n",
// etc
}
}
snmpbulkwalk.c:
if (check && snmp_oid_compare(name, name_length,
vars->name,
vars->name_length) >= 0) {
fprintf(stderr, "Error: OID not increasing: ");
// etc
}
The command-line tool picks up on anything other than
strictly increasing OIDs. The perl module only spots
a repeasted OID (so wouldn't recognise your situation,
where the OID actually goes backwards).
Try tweaking the SNMP.xs code to use the test "<=" instead of "==",
(since the two OIDs are presented in the opposite order!)
recompile, and re-install. Does that make any difference?
