That's all. BTDT. In INN, a common occurrence in servers with a combination of too large an active file (which is rewritten to disc too often) and too heavy an article arrival load will cause the "overchan" process to backlog. Eventually, innd's attempt to shovel data at the too-slow overchan causes it to barf and complain about it, dropping a copious blob of yet-to-be-dealt-with overview data in /var/spool/news/outgoing and uttering a nefarious complaint in the news server log. Solutions: - "renice -20 " (you'd be surprised how much it helps) - More server horsepower: Bigger memory, faster CPU, better discs. - Trim the active file to remove groups that genuinely have no one reading them. - Reduce the incoming feed. Honestly, #3 is something that I ended up doing for unrelated reasons a couple years ago. On that day, my news server, INN 1.7.2+insync running on a PPro 200MHz w/128Mbytes + 2*9G RAID0, went from sweating at 95+% busy-ness, all day every day, to jogging comfortably at ~70% busy-ness, according to the timer stats in the daily report. I haven't had a problem with it since. --karl
