Re: problem in SNMPSET on table with string data type columns

I've had trouble with multiple requests in ordered table_iterator tables.
 I have no idea if that's what you're using, since you didn't give much
info about your use case.  I just worked around it by injecting the
serialize handler:

    int result = netsnmp_register_table_iterator( reg, iinfo );
    assert( result == MIB_REGISTERED_OK );
    int injected = netsnmp_inject_handler( reg,
netsnmp_get_serialize_handler() );
    assert( injected == SNMPERR_SUCCESS );
