[SNMP4J] Frank - Need help Urgent!!!!!!

[Frank Fock]

Hi Eva,

How do you destroy threads? Are you joining them (the only clean
solution)?

In general, I would not use 22 threads to receive 22 rows of a table.
This is not efficient. Using a single GETBULK request with max repetitions
set to 22 would be much better.

Best regards,
Frank
