Hi Andrea,
Sorry for my late reply, I've been trying to get a machine to run 2.1.123 so I can do more than run my sample test program (which you did anyway and we know is running fine). I've also been off the net for a good 12 hours and now I'm getting bombarded with linux-kernel mail. :-)
For starters, I've been running 2.1.123 (unpatched) on the local news server to see how well it can handle the load, and so far so good. I expect to be able to test the patch in maybe a couple of days.. It would be really great to have this problem fixed, as right now it takes 30-60 seconds for innd to fork and exec nnrpd when a new reader connects to the server. And you can imagine how annoying that is for users. :-(
Thanks again, I'll let you know as soon as I have the server running with your patch. Hopefully the results will be good. :)
Ion
