We have around 3000 uucp feeds of mail and some subset of newsgroups hanging off of a P90/FreeBSD box. I used a single feed out of INN that is taken to a special exploder I developed. This exploder creates the individual batches which are then delivered into the uucp accounts with that Frenchy sendbatches package. This single feed out of INN is necessary because of some problems with managing the large number of file descriptors that would have been required. INN has at least one and probably two file descriptor leak bugs. I have a patch for one of them that does make a big difference in the robustness of INN with a lot of feeds. I had originally tried to use Solaris X86 to do that and had some level of success. INN under Solaris was able to use MMAP and I miss that with the FreeBSD. Unfortunately the Solaris TCP/IP implementation had some flaws that caused hangs and core dumps ect. It was even more frustrating for me because I couldn't really lift up the hood and find out what the problem was. We experimented with Linux and FreeBSD, finally settling on FreeBSD. I'm now very happy (with sources !). FreeBSD handles the heavy load quite well and its nothing short of amazing. Salutations to the FreeBSD team. Even without MMAP the INN resource utilization does not appear hampered and the batching of the individual feeds goes faster than the Solaris box. I have only one more SYSV era machine to convert to the new era. Good Luck, Mark Hittinger bugs@win.net
