I configured freeswitch (FreeSWITCH Version 1.5.15b+git~20141117T202539Z~424df19083~64bit) on Ubuntu 12.04. It works properly. I’m using xml_curl module to generate the dialplan. Then I set  the media bypass parameter on freeswitch  dialplan. But the freeswitch  crashed when following dialplan was given.

In here I ‘m using attendant transfer feature.

Here I have attached the print screen of freeswitch console  just after  it  crashed.

Kindly advise me to solve this problem.
