location update problem

hi, i got a leak of channel ressource. (currently i cannot look at the source code.) ignore the first 3 lines, they are just part of testing/debugging code i use. after location update fails. "DB: Failed to find the Subscriber...", get an "ERROR INDICATION" with cause 1. it seems that the mobile just stops sending on the channel. the channel ressource hold by location update process is not freed. the last messages show that. i will look on this the next days and report if i found something. if you have any idea, please tell me. the way to test any change/fix is quite complicated. the bug only occurrs when many phones are available and when they move from a different network to my network (built in a car, moving arround.) andreas <8000> chan_alloc.c:164 looking for free signalling subchannel on CCCH <8000> chan_alloc.c:168 requesting SDCCH* channel <8000> chan_alloc.c:135 free lchan (1) found on trx 0 ts 1 <0010> abis_rsl.c:894 Activating ARFCN(123) TS(1) SS(1) lctype SDCCH chan_nr=0x49 r=LOCATION_UPDATE ra=0x15 <0010> abis_rsl.c:744 channel=(bts=0,trx=0,ts=1) chan_nr=0x49 CHANNEL ACTIVATE ACK <0001> abis_rsl.c:988 channel=(bts=0,trx=0,ts=1) chan_nr=0x49 ESTABLISH INDICATION <0004> gsm_04_08.c:1528 LOCATION UPDATING REQUEST <0004> gsm_04_08.c:1200 LUPDREQ: mi_type=0x04 MI(1293316309) type=NORMAL <0002> gsm_04_08.c:347 lchan (bts=0,trx=0,ts=1,ch=1) increases usage to: 1 <0004> gsm_04_08.c:1226 <0002> gsm_04_08.c:990 (bts 0 trx 0 ts 1 pd 05) Sending 0x18 to MS.
