[AGENT++] agent stopped after changing the snmpversion

[Frank Fock]

Hi Venkataraman,

Sorry, I was mislead by the brace indenting. Jochen has found
the cause correctly.

You can modify the VACM at runtime. Getting a global lock
with mib_lock() is a good idea when doing so.
In any case, the VACM can be modified through SNMP
message from an authorized user at any time.

Best regards,
Frank
