when the usb stick I'm using is receiving a sms the gammu-smsd service freezes two times. First for about 40 seconds and then for a few minutes.

Then - after a few minutes and succefully reading the sms - something really weird happens: The connection to the remote database is lost and gammu isn't able to connect anymore. Instead of using the host that's specified in the config file it now tries to connect to the wrong host: the routers public host name (what you get when using nslookup on your own public ip).
The service has to be killed and restarted to work again. Everything else using network is working fine, it's just the gammu service.

gammu version 1.38.1-1 und Debian (Raspbian on RaspberryPi, kernel 4.9.80)
The UMTS stick is Alcatel X602D.

It freezes before the line:

gammu-smsd[30481]: gammu: [Retrying 1 type 0x00]

And the network error is basically:

gammu-smsd[30481]: Error code: 2006, Error: MySQL server has gone away
gammu-smsd[30481]: Reconnecting to the database!
gammu-smsd[30481]: Reconnecting after 1 seconds...
gammu-smsd[30481]: Error connecting to database!
gammu-smsd[30481]: Error code: 1045, Error: Access denied for user 'username'@'' (using password: YES)

(and of course access is denied, there's an sql server running on the wrong host too)



Thank you!
