Kprop Eating Disk Space?

I have a master kdc and a slave kdc. In the master kdc, I run a script that executes kprop to propagate the database to the slave every 2 seconds (for testing purposes). On the slave kdc, I run the "df" command periodically. I noticed that the disk space percentage usage climbs up slowly. Eventually, it goes up to 100%, and my slave machine crashes. I don't understand how/why kprop could cause the disk space in the slave machine to go up because the master database is always the same size. If I stop the propagation, the disk space in the slave doesn't go down, until I reboot the machine.
This is sample output from the "df" command:
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/mtdblock3 14976 13436 1540 90% /
This is sample output from the "mount" command:
/dev/mtdblock3 on / type jffs2 (rw)
/proc on /proc type proc (rw)
none on /dev/pts type devpts (rw)
/dev/ram1 on /tmp type ramfs (rw)
/dev/ram2 on /var type ramfs (rw)
Perhaps, this is a different problem that doesn't have anything to do with kprop, but I only see this happening when I run the kprop script. Does anyone have any clues about this strange problem? I'm not familiar with how the kprop process works. If someone can give me a general overview of the process that occurs when the master database is propagated to the slave kdc, that would be tremenously helpful. Thanks for your time and help.
