Thanks for boxbackup. It's a great tool that has saved me several times.
I run bbackupd 0.09 on freebsd 5.4. It has been running somehow stable for
several months. It sometimes crashed, but I can just restart it as if
nothing happened. No system changes have happened for long time.
Recently bbackupd began crashing soon after starts up. It always crashes
on the same file, even though there have been no changes to the file. I
have tried to remove the file it chokes on; bbackupd then runs a little
longer but chokes on a different file. Both the debug and no-debug version
of bbackupd stops at the same point.
To run 'bbstoreaccounts check 1234 fix' on the backup server did not help.
To reboot the backup client did not help.
syslog says:
kernel: pid 7330 (bbackupd), uid 0: exited on signal 5 (core dumped)

In this case, bbackupd stopped on a directory. Checking the file system:
# ls -ld /usbdisk/home/sauber/projects/dev/linker/htdocs/.p/scene2/CVS
drwxr-xr-x 2 sauber sauber 512 Sep 4 2000 /usbdisk/home/sauber/projects/dev/linker/htdocs/.p/scene2/CVS

Obviously I would like to get bbackupd up and running again. Please let me
know if I can provide any other information.
Thanks,
