AgentX++: Subagent Reconnect does not work

[Frank Fock]

Hi Christel,

The reconnect does currently not properly work. This will be fixed soon
with a AgentX++v1.3 which will be released together with
AGENT++v3.4.7.

With a few modifications, you can get the current code work as well:
1. Insert "stopit = TRUE" within AgentXSlave::receive whereever
connection loss is detected. Remove the "raise(SIGTERM)" and
set the error level of the LOG_BEGIN statement to 1.
2. Change "void Mib::init()" to "boolean Mib::init()". This must be
changed in MasterAgentXMib and SubAgentXMib accordingly.
The new init() method should return TRUE if initialization (reconnection)
was successful.

Hope this helps?

Best regards,
Frank
