Hello,
my snmp application is created as a Dynamically Loadable Object and
i try to do an multiple snmpget request on my implemented table with 8 colums and i've got the error 'No Such Instance currently exists at this OID' on some column entries. It seems that only the STRING columns followed after the first string column failed. Also If i request a wrong column index on multiple snmpget request snmpd crashed with segfault.
If i do an snmptable request or a single snmpget request on all columns all data correctly response.
Multiple request failed (1-9) -> column 9 does not exist:
snmpget -c public localhost 25.3.3.1.sysModInfo.0x8801 25.3.3.1.9.0x8801
snmpd -f -Le

What
Here is the code of my table handler function:

table_entry = (struct moduleParamTable_entry *)
netsnmp_extract_iterator_context(request);
table_info = netsnmp_extract_table_info( request);
switch (table_info->colnum)
{
case COLUMN_SYSINFO:
if (!table_entry)
{
netsnmp_set_request_error(reqinfo, request,
SNMP_NOSUCHINSTANCE);
continue;
}

break;

}
Can anybody help me?
