Subject: SUMMARY: `rn' consuming 100% CPU whilst doing nothing...
Yesterday I asked the following question on the net and today I'm a happy man
again... ain't life with computers wonderful?
> `rn' to read news hasn't been working for a week (and I've been away...) and
> my users are now getting dead worried that they'll lose news. Basically what
> happens is that `rn' just stops and the CPU meter goes to 100%. `top' shows
> that `rn' is busy doing something, however, to the user it's doing nothing
One of our brothers from Sweden, Svante Lindahl <sl@os.se> hit the nail on the
head with:
> This is just a wild guess, but could it be that the internal hash table in
> rn has been outgrown? I think there are two defines in rn's common.h that
> you might like to change. They are MAXRCLINES and HASHSIZ. To see if that

Indeed it was! So I changed the following definitions:
#define MAXRCLINE 1500 /* number of lines allowed in .newsrc */
/* several parallel arrays affected. */
/* (You can have more lines in the active file, */
/* just not in the .newsrc) */
#define HASHSIZ 1653 /* should be prime, and at least MAXRCLINE + 10% */
to 3000 and 3351 (3351 *is* prime...?), typed `make' and `make install', and
off we went reading News again! Tackar saa mycket, Svante.
Also many thanks to "Susan Thielen" <thielen@irus.rri.uwo.ca> and lemke@MITL.COM
(Kennedy Lemke).
