I am using 2 asterisk 1.4.21 boxes. the main one every 20 seconds does an outgoing call file to the second box and speaks a wav file over the console/dsp. Works for A LONG TIME then seg fault. I have posted a bug report but to date there has been no action. I tried to see if there was some thing simple by attaching to the process with gdb but it is not showing up. Was wondering if the list had any suggestions. Thanks. Jerry ----------------------- Program received signal SIGSEGV, Segmentation fault.
