Can you give me some solutions or questions?

A few things:
- Can you upgrade to 0.9.14 and see if the issue still exists?
- Can you put guacd in debug mode (/path/to/guacd -L debug) and see if you get any more useful error messages?
-  The abrt-hook-ccpp and abrt-server messages aren't actually from guacd, they are from a process on the system which watches for processes that crash in a certain way and collects crash information about those processes.  The following page contains information on this tool and how you can use the files generated to analyze the cause of the crash:
