I had this issue with 1.2.22 and did a yum update to 1.2.23 but it still exists. I also tested that the segfault happens regardless of having "sticky" aliases or not. Am I doing something wrong perhaps? Does anyone else have this problem or is it somehow exclusive to my system? ------------- # cat /etc/redhat-release CentOS release 6.5 (Final) # uname -a Linux fax 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux # fs_cli freeswitch@internal> alias del nonexistantalias Socket interrupted, bye! # ps aux | grep freeswitch root 775 0.0 0.0 103244 832 pts/1 S+ 10:02 0:00 grep freeswitch # tail /var/log/messages ...
