Hi KeKe,

Alex again.

I am wondering, if a sms modem could enter sleep mode for few days of working and smsd cannot check for modem's readiness. If it could go into sleep mode, is there any settings in smsd.config could protect from this?

Thanks for your help in advanced.

Best regards,
Alex Kent

There is no sleep mode.

For some reason the modem process was killed at 2011-05-19 16:19:35, and I do not know the reason for that. Latest activity with a modem was about three hours before, and because your system is not receiving messages, modem process has been idle and just waiting for messages to be sent. Before a modem process got killed, there was no any errors with the modem, which means that some external process (or user) is killed it.

Is this happened more than once?

Hi Ke Ke,

Thanks for the prompt reply.

This happened for the first time. I will update you again, if it should happen again.

By the way, Is there any sample scripts to perform following function:

- Send email to specific person whenever the sms process/service is being stopped.

As far as I remember, no complete samples are published here, but Nagios could do the job with check_procs plugin.

Thanks...
