If you look through the output of snmpwalk, how will note that the last 
"oid" when sorted in lexicographic (dictionary) order starts with 
"Client DNS"

So a getnext with svSvcOperatingState.10  looks for the lexicographic next 
for the ASCII code 10 which would be "C" in this case - the exact entry 
being "Client DNS"

This is part of the reason we had a discussion a couple of months ago 
about supporting getnext or "getcolumn" functionality in check_snmp
on nagiosplug-* lists.

Some design work has to be acomplished to support it effectively because 
of the existence on sparse tables in some mibs. Specially because we don't 
want to implement a MIB reader to figure out the column vs index oid 
values.

As a different solution have you tried NSClient to see if a particular 
process is running ?
