Summary:                    Asterisk core-dumps if used as loadgenerator using
callfiles
Description: 
A perl script is used to generate asterisk call files. 1500 "Asterisk
Clients" are connected to another SIP-Softswitch.

A calls B and on both ends RTP will be played. Call files are written with
"modify" time, this allows to limit the calls per second.

./load_generator.pl -f numbers.txt -cmax 250 -cps 10

Asterisk restarts with about 300 active calls:

/usr/sbin/safe_asterisk: line 146: 15582 Segmentation fault      (core
dumped) nice -n $PRIORITY ${ASTSBINDIR}/asterisk -f ${CLIARGS} ${ASTARGS}
>/dev/${TTY} 2>&1 </dev/${TTY}
Asterisk ended with exit status 139
Asterisk exited on signal EXITSTATUS-128.

It doesn't seem to be an Asterisk issue; rather, the "@plt" string in gdb
indicates that the PLT in the linker is at fault.  Quite simply, the linker
cannot find the ao2_unlock function.  This is rather strange because the
PLT is used for lazy linking of symbols, which is not the linking type
requested for ao2_unlock() in our Makefile and may point to other
problems.

You need to report this error to your distribution vendor, as a problem in
their linker tools.
