Hi, for some reason my Asterisk has been crashing recently. I've not made any changes to Asterisk itself, although I did attempt to get the asterisk <> RT gateway working a few days ago, which required me to install an AGI file (now removed) and also install Asterisk-Perl? Anyway, I'm getting dump files in /tmp , when I run them through GDB, I see the following: #0 get_bit_raw (fskd=0xf69fa008, buffer=0x9062000, len=0x75b8838) at fskmodem.c:34 #1 0x080865b8 in fsk_serie (fskd=0xf69fa008, buffer=0x9052374, len=0x75b8838, outbyte=0x75b8838) at fskmodem.c:250 #2 0x08082c3d in callerid_feed (cid=0xf69fa008, ubuf=0x75b89c4 "??????????", '?' <repeats 27 times>, '?' <repeats 12 times>, "???????????????", '?' <repeats 20 times>, "???", '?' <repeats 50 times>, '?' <repeats 13 times>, "?????????????????????????", '?' <repeats 11 times>, "??????????????"..., len=-157310968, codec=4) at callerid.c:258 #3 0x004c1fb8 in ss_thread (data=0x8fedcd0) at chan_zap.c:5144 #4 0x00788cce in pthread_start_thread () from /lib/i686/libpthread.so.0 #5 0x00e5d57a in getloadavg () from /lib/i686/libc.so.6 Now I am no expert but it looks like some junk is being fed to caller ID which may be causing asterisk to bomb out? I'm running a slightly modified version of zaptel to cope with the silly UK caller_id, however this has been working extremely well for some months now. Thanks for any pointers, Mike
