Ok that means the perl script exited before it should have. If you start it
using "perl backuppcfs.pl -f <mountpoint>", it will keep running in the
foreground and print out any errors that occur.

One reason why it may have exited is Out of Memory - in case someone/something
would try to read through the whole directory tree in a short time, the tree
cache will probably start using arbitrary much memory. Next on my todo list:
limit the amount of the tree nodes held in memory.

If it's caused by something else, i'd like to see the error message.
