We're running USENET on a dedicated SS20 server running Solaris 2.5.
Recently, we upgraded our version of INN to 1.5, and are now having memory
problems. Has anybody had similar experiences? Are there any interesting
options I can set in config.data to make things run a bit better?

WARNING: Babbling technical details follow

I had a script lying around that ran "/usr/ucb/ps -augxww" and averaged the
SZ and RSS columns for all of the in.nnrpd processes running, along with
its output under INN1.4unoff1, and it looks like the in.nnrpd that came
with INN1.5 uses about 3 times as much resident memory as the older
version:

Old version:
PROCS MEM RES AVGMEM AVGRES
58 181296 59300 3125 1022
New version:
PROCS MEM RES AVGMEM AVGRES
56 179936 162400 3213 2900

(where PROCS is the number of in.nnrpd's running,
MEM is the total memory used by the in.nnrpd processes (SZ),
RES is the total resident memory by in.nnrpd processes (RSS),
and the two AVG columns are just totals)

Thanks for any comments/information/ideas,

------Scott.

How much memory does this system have?

Perhaps INN 1.5 includes teh "shared active" patch whcih causes the in.nnrpd
processes to share much more memory so they can have more stuff resident
each (as resident pages are counted for each process and shread pages are
counted as many times as they are shared)

No, sharedactive patch is not a part of official INN 1.5{.1}

We use nnrpd with sharedactive, and I saw nothing strange
after installing the last nnrpd - approx. the same sizes.
