now phone number 6 is crashed. I started the osmocon processes in a screen 
session. A lot of messages are loged now in the session like this:

[...]

And mobile says:

OsmocomBB# show ms 6
MS '6' is up, service is limited
   IMEI: XXXXXXXXXXXX
      IMEISV: XXXXXXXXXXXXX
      IMEI generation: fixed
   automatic network selection state: A1 trying RPLMN
                                      MCC=262 MNC=07 (Germany, O2)
   cell selection state: C2 stored cell selection
   radio ressource layer state: idle
   mobility management layer state: MM idle, PLMN search

I now restated the mobile process and deleted 6.ba. Now it says:

OsmocomBB# show ms 6
MS '6' is up, service is limited
   IMEI: XXXXXXXXXXXX
      IMEISV: XXXXXXXXXXXXX
      IMEI generation: fixed
   automatic network selection state: A1 trying RPLMN
                                      MCC=262 MNC=07 (Germany, O2)
   cell selection state: C1 normal cell selection
   radio ressource layer state: idle
   mobility management layer state: MM idle, PLMN search

shutdown/no shutdown doesn't change a thing.

Now the question again: Could it be because of my hardware situation 
(special battery simulation with one power supply)? Or in other words has 
anybody running a steady service with osmocombb and experiences no problem 
over weeks?

Thanks
