[Freeswitch-users] Problems with mp3 larger than 70MB while playing files into the conference in the "perpetual-sound" variable

Mon Feb 14 17:27:41 MSK 2011

Bug url = http://jira.freeswitch.org/browse/FS-3053

Hello guys, me again. Now with another bug that i found.
I set the "perpetual-sound" variable in the conference.conf.xml to play mp3
files that my customer chooses.
but when a mp3 with 71mb or more is played, it crashed the machine when was
more than one user listening to the mp3.
i tried a file with 99mb and crash too.
but when i use a file with 10mb or less, works fine.

i looked at the core file and see this:
