petmar: You're right, either a driver problem or that power supply on the usb hub. Hopefully the modem driver guys will respond soon.
Thanks for your time.

petmar: Well, at the moment I don't know what's going on there. I'm on a Win/Cygwin setup with usb modems. After some time sms server stops communicating with modems (one after another) until only one of them is online - this is randomly. There is no error reported in the logs even with the highest loglevel - the modem just stops responding:
2009-06-15 13:51:06,6, LOGIGSM1: Checking device for incoming SMS
2009-06-15 13:51:06,6, LOGIGSM1: Checking if modem is ready
2009-06-15 13:51:06,7, LOGIGSM1: -> AT
and after that nothing ...
I'm suspecting that there might be a problem with power supply of the modems - if there is only one pluged in the system works great, no problems, no errors, ... When I start adding modems the problems start to appear. I have shipped a new externally powered USB hub with higher rates on output voltage on the adapter to that location, hopefuly it will solve the issue.
EDIT:
I forgot - sometimes there is following line recorded before what's mentioned above:
2009-06-15 13:50:56,6, LOGIGSM1: No SMS received (reading interrupted)

petmar: Thank you, my problem is not about the time needed for restart - just we have monitoring setup on the smsd log file and every shutdown generates an alert in the ticketing system and I need to avoid that when only some of the forked modem processes get stuck and I have to somehow restart it ...

petmar: Hi, is it possible to start/stop handlers for individual modems in a config with multiple modems so I do not need to restart the server with modified config?
