Hi ***** - Enable coredump http://blog.urdada.net/2007/12/31/71/ ***** - Find it after next crash ***** - Analyze coredump First, when i say crash, it's a panic in USB, not a crach of daemon/executable. This is because Freeswitch/GsmOpen is attached in TTY and lock the TTY, blocking other processes to manage USB (tty). ***** Find what is calling USB modem power off and disable it.***** No poweroff, no error. Some modems power off and power on again, i try to find what is causing this error, without success. Maybe some errors in power suply or modem just reset, because i try it with 4, 10, 20 and 30 modems, and the problem persists. In my search, google and other forums, i found someone talking about modem resetting for own. Sometimes the user wan't to change de SIM in modem, and remove it and put it again, without make a dettach in my interface/system. Or if he not remove the modem and just change de SIM (o.O), its a request of many users of my system using E303 or other modems. I identify this, because i'm attached in ttyU0.0, ang get event im my source or a CME-ERROR 10, if modem just changed SIM, then i reset the modem with AT command ^RESET. I'm using mod_xml_curl to get interfaces info, and ESL events to manage this... Then i make a "gsm remove xxxx" and when modem arrive i make a "gsm reload". This way not affect the calls in progress. I talk with Shlomi Agiv, and apply some functions of his patch, now i'm just making tests.... Now i'm having some problems, just when i call a "gsm remove" in ESL, its stop to reply, even when i send other command, like "sofia status". It's the same when i send command with fs_cli... Before ask, i make some debugs, change source, put log and other things.. I ask, because some times other people have the same problem!
