utils/kamctl: new command 'trap'
- useful to get a full bt dump of all kamailio processes
- handy in dead-lock investigatigations
klaus,
thanks for the pointer. i pulled out shell script from it (below).
it would be still nice to know how kamailio is dispatching the requests
to worker processes.
-- juha
#!/bin/bash
BINARY=kamailio
GDB=gdb
DATE=`/bin/date +%Y%m%d_%H%M%S`
LOG_FILE=/tmp/gdb_kamailio_$DATE
echo "Trap file: $LOG_FILE"
pres-serv_ctl ps > $LOG_FILE
echo -n "Trapping Kamailio with gdb: "
PID_TIMESTAMP_VECTOR=`sed -e 's/\([0-9]*\).*/\1/' $LOG_FILE`
for pid in $PID_TIMESTAMP_VECTOR
do
echo -n "."
PID=`echo $pid | cut -d '-' -f 1`
echo "" >> $LOG_FILE
echo "---start $PID
-----------------------------------------------------" >> $LOG_FILE
$GDB $BINARY $PID -batch --eval-command="bt full" &>>
$LOG_FILE
echo "---end $PID
-------------------------------------------------------" >> $LOG_FILE
done
echo "."
