Thanks a lot! The log was gotten by after I clean the log file and start kamailio. Let me send you another successful start log attached without doing patching (version 5.5.4) . And I think I did not use custom patches. What I did is only executing apt-get update & apt-get upgrade commands. When I execute the command, 'apt-cache search kamailio ', it shows 45 patches (modules). But I installed only 11 modules before. In the word document attached you will see the 11 modules with green color. I am not sure if the other patches(modules) except 11 installed before will fork a new process (child) and this new process will cause problems to the main process? Really thanks for your kindly reply and apologize for the troule I brought to you.

If you do a system upgrade for a package that consists of several individual packages, like Kamailio, you usually should update them all together to the same version. Otherwise, you’ll end up with some problems in many cases. So, I’d suggest using the tools of the package management (like apt or dpkg in your case) to verify the version of the installed kamailio. If you send some log files, best is to include them in the actual e-mail, or use a text file. Word files are not optimal as some people cannot open them.
