Upgraded net-snmp to 5.3.1
Operating system rd7.3
Table function handler fails to loop thru multiple OID's in the same snmpget command.
snmpget -v2c -c public localhost enterprises.103.1.9.2.5.1.2.1 enterprises.103.1.9.2.5.1.2.1 enterprises.103.1.9.2.5.1.2.1 enterprises.103.1.9.2.5.1.2.0
The handler gets called, but the for (request = requests; request; request = request->next) does not loop through the OID's. The first value is returned correctly, but all subsequent values return the table row index.
Scalar variables work fine. Let me know if there is any other information that can be of assistance.
Thanks.
Below is the initialization function. The number of table rows can very from 5 to 20 depending on implementation.
