Hi,
my GSM-IP-modems are getting stuck after some time. If there is no activity for a special duration and then an sms has to be sent, the modem is not reacting anymore:

2013-05-21 08:51:55,6, GSM_IP_1: I have to send 1 short message for /opt/smsservertools3/data/checked/20130521_085149_smsgw.out.DCdfNG
2013-05-21 08:51:55,6, GSM_IP_1: Sending SMS from to 4917********
2013-05-21 08:51:55,6, GSM_IP_1: Checking if modem is ready
2013-05-21 08:51:55,7, GSM_IP_1: -> AT

Waiting for now 90 minutes didn't solves it.
The sms-processes are not ok as well I guess:
sms 15790 1 0 May17 ? 00:00:08 /opt/smsservertools3/bin/smsd -n MAINPROCESS -p/opt/smsservertools3/smsd.pid -i/opt/smsservertools3/smsd.working -c/opt/smsservertools3/config/smsd.conf -l/opt/smsservertools3/logs/smsd.log
sms 15792 15790 0 May17 ? 00:00:09 [smsd] <defunct>
sms 15793 15790 0 May17 ? 00:00:10 /opt/smsservertools3/bin/smsd -n GSM_IP_2___ -p/opt/smsservertools3/smsd.pid -i/opt/smsservertools3/smsd.working -c/opt/smsservertools3/config/smsd.conf -l/opt/smsservertools3/logs/smsd.log
r

Is there a way to get more information to narrow down this issue? Or any hint how to solve this immediately?

Kind regards,

Problem solved.
There is a timeout-parameter inside the gateways - when disabled, everything works fine. when enabled (parameter set in minutes) the gateway cuts the connection. sms server tools need a restart to reestablish the connection again.

kind regards,
