Hi Dave,
Actually I have 2 tables, and on both it behaves differently.
Let's say on Table1, snmpwalk displays all the contents of the table without
problems, once the last field is displayed, snmpd hangs in there without
response, and then it shuts down.
On Table2, snmpwalk command will not display any contents, snmpd hangs in there
without response, and then it shuts down.
On both tables, if I perform snmpgetnext, it works fine. If I snmpwalk to each
column on both tables, it works fine too.
I'm going to try to revert table 1 using the netsnmp helper handler instead, to
check if this happens with the helper as well. Then, I will DEBUGMSGTL to
check where it hangs...

No.
Do you see the whole of the table before the agent hangs?
Or does it stop somewhere in the middle?
If you restart the agent, and then issue a single "snmpgetnext"
request on the last entry in the table - what happens?
Do you get anything back, or does the agent hang again?
If you get something back, then what?
If it hangs, what is the next registered object in the agent?
