I wasn't sugesting removing /etc/cron.daily/prelink. If you look at
the above commands - they are:
- remove /etc/prelink.cache
- run /etc/cron.daily/prelink (which should do a full prelink - and
recreate /etc/prelink.cache)
Ideally the memory usage (used [-/+ buffers/cache] + swap) shouldn't
change with the above commands - but it does!. I have no good
explanation for this behavior (other than the speculation that the
kernel uses some memory - and this is released on a BIG I/O operation)
