Hi ! Master I wrote a auto dial out program named waihu5. It's main function is fetch phone number from Oracle DB using unixODBC, then call a tuxedo services to verify the phone number.When the verify is passed, update database status for this phone number . Finally ,when receive the HANG-UP event for this phone number, get Hangup-Cause and again update database status for this phone number. It was runing perfect this morning for 1.5 hour,and processed and dialed out about 10000 phone number. But this afternoon,when it has finished 16000 phone number,it's crashed! I just don't know how to fix it?Can you help me. Here is crash info:http://pastebin.com/3xTk0GgN I have no dump file .I think since it was crashed ,it will crash again .Then i will get crash file,because i have about 90000 phone number to dial out. So if you know where is the problem ,please tell me. Thanks a lot! My english is so bad,i wish you can understand what i said. Thanks again.
