Problems
----------------------
1. I'm running a High-water-mark/Low-water-mark space based
expire program with simple warp acceleration to meet diskspace
requirements. Sometimes during my expire process, my news.daily
cron job kicks in. I wind up with an "Out of memory!" error in
my "/var/log/news/errlog" file. I'm running 384MB RAM and 855
swap.

megabytes.

megabytes.

I suspect a memory leak in expire or in INND itself but can find
no evidence. Anyone with previous experience or suggestions on
tracking down this problem is welcome.
--------------------
2. I'm running into a nearly 4 hour expire time which seems
excessive. Does anyone know a way to improve my expire times?
My present expire command looks like:
/var/news/bin/expire -p -v1 -l -n -w 0

Any help is greatly appreciated.
