If you are running out of inodes, you should mkfs with more or, if it's
the inode bug, fix it.  But this script will help.


#
# This demon script (uukill) watches for a lack of space and kills incoming o
# uucico jobs when space is low.
# This is done to prevent a site from sending
# more usenet news than this system can handle.
# Written for HDB uucp.  Non HDB uucp systems may be able to get the pid
# from the TM file name.
#
# Run from /etc/inittab with:
#
#    uk:23:respawn:/etc/uukill
#
