If so, are you running Zaptel 1.4.2? I had this same crash happen using zaptel 1.4.2. Updating to 1.4.2.1 fixed this. -- Steven Haigh Email: netwiz at crc.id.au Web: http://www.crc.id.au Phone: (03) 9017 0597 - 0404 087 474 There is a TDM2400P in the machine, but it is running the 1.2 branch. It is running Zaptel 1.2.13. _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
