Subject: INN trouble with too many files open
Sender: owner-hackers@freebsd.org
X-Loop: FreeBSD.org
Precedence: bulk

Hello,

I have made a news installation with the 2.2-960801-SNAP and INN 1.4unoff4 .
I am receiving a streaming feed from one site, and whenever that site starts
to feed me, my innd throttles after a while, with a message:

Server throttled Too many open files writing article file -- throttling

The weird thing is, that I have already compiled a kernel with maxusers set
to 256, and that I have used sysctl and set the maximum number of files to
20.000 , but it didn't help. I must have overlooked something. Here is the
output from sysctl:

Any ideas ? All help is appreciated.
