https://origsvn.digium.com/svn/asterisk/branches/1.4 ................ r72852 | crichter | 2007-07-02 10:41:08 +0200 (Mo, 02 Jul 2007) | 9 lines Merged revisions 72585 via svnmerge from https://origsvn.digium.com/svn/asterisk/branches/1.2 ........ r72585 | crichter | 2007-06-29 15:08:26 +0200 (Fr, 29 Jun 2007) | 1 line check if the bchannel stack id is already used, if so don't use it a second time. Also added a release_chan lock, so that the same chan_list object cannot be freed twice. chan_misdn does not crash anymore on heavy load with these changes. ........ ................ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@72869 65c4cc65-6c06-0410-ace0-fbb531ad65f3
