For last two kernels I got a deadlock within 5 minutes of newsfeed starting up, so something might have changed, from crash and filesystem corruption to deadlock. August 19 kernel still runs with no serious problems. Has anyone got a news server running reliably with kernels later than end of August (preferably ones with tag RELENG_2_2) ? It seems odd that I can repeat this so easily, I would assume a lot of people should see this ? I have gotten metoos from (only?) three people now. This problem has been there for about 2 months now. The system is 3940, seagate Hawks for news disks, P120 ASUS TritonII, 96M. Exports two NFS disks (not the news partitions).
