I have run the urbackup server happily the past several days, however in this morning, a crash happened, the log is attached. I seems that a null point is dereferenced…

The Linux distro which the urbackup server run is Debian 7.1.0 X86_64.

Can someone help?

How many clients do you have? There is a bug with a moderate amount of clients on Linux in 1.2.4. You could try 1.3: https://sourceforge.net/projects/urbackup/files/WorkInProgress/
