qqq:
I think that pppd should not use the same port which is used by smsd.
smsd at ttyUSB2 and pppd at ttyUSB3
Original poster have had the following issue:
2012-04-02 10:29:43,3, smsd: FATAL ERROR: Looks like another smsd (29206) is running. I (1969) quit now.
Problems were caused, because smsd was started more than once.
I think it's not may case, I using sms3 start/stop script.
Maybe there are two different issues in original poster's problem: io error when modem disconnects and smsd double-starting?..

qqq: "communication_delay = 5" has no effect
still get "USB disconnect" then:
GSM modem (1-port) converter now attached to ttyUSB0
GSM modem (1-port) converter now attached to ttyUSB1
GSM modem (1-port) converter now attached to ttyUSB3
GSM modem (1-port) converter now attached to ttyUSB4
GSM modem (1-port) converter now attached to ttyUSB5
Should be ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3, ttyUSB4 (smsd use ttyUSB2)
May be some port open options affects on ttyUSB2 disappearing? There is pppd at the same time working on ttyUSB3 but there is no such problem with it
P.S.
Not related to this problem but it will be good if smsd have port locking option with /tmp/LCK..ttyUSBx file

qqq: Hello,
I have the same problem on 5 machines with the sim5360 modems. Did anyone fix it?
All machines worked fine for half a year with the modems, but as soon as I started using smsd I faced this problem.
