AgentX++: Problems with raise(SIGTERM) ?

[Frank Fock]

Hello Christel,

I do not see any problems with your approach to catch the SIGTERM
signal and trying to reconnect to the master, but you should consider, that
the current implementation of SubAgentXMib::init() does no retries and
assumes that the master agent is accepting connections. So you will have
to introduce a delay and a timeout in order to prevent endless looping.

Best regards,
Frank
