This code should have been executed in that case. Did you see this message in your log:
if (request || var) {
/*
* ack, this is bad. The # of varbinds don't match and
* there is no way to fix the problem */
if (pdu)
snmp_free_pdu(pdu);
snmp_log(LOG_ERR,
"response to proxy request illegal. We're screwed.\n");
netsnmp_set_request_error(cache->reqinfo, requests,
SNMP_ERR_GENERR);
}
Yes, I do see this. (It's there in my perhaps overly lengthy 1st msg.) I've been looking at this code for something left in a strange state but I don't see anything yet.
I again but without using the bulkget. Instead I sent an SNMPv1 getnext for the same two OIDs to snmpd. Same problem. Here's a trace from just before the "we're screwed" log:
