I'm persistently getting ENOBUF on the news machine, usually from ctlinnd. I haven't yet upgraded to 1.5.1; we're running unoff4. netstat -m always has a comfortable number of clusters and also always reports 0 requests delayed or denied. This seems inconsistent :-) A 1.5.1 upgrade is due today; it is a bit complicated by the change to the file layout :-( (this started when we added a feed that tends to open 6 streams at a time; it apparently has to do with thenumber of sockets open at once. INND is indeed behind reading from the streams but since netstat -m always reports lots of free memory I can't figure out where the particular ENOBUF is coming from - there are about a hundred occurences of this error in a quick grep of the kernel source.) Is there a kernel tweak other than the listen count and nmbclusters that may apply here? Both of those have been increased greatly. Also, is active file mmap safe to use in 2.1.5 or do I need to use 'read'? I got burned once (in irix 4.0.5) where the innd config said to use mmap but innd cored a lot until I converted back to read. This isn't happening here but innd is grossly behind, at only 1-2 articles/sec. Thanks in advance, -- Pete
