Lines: 30 In-Reply-To: rees@pisa.ifs.umich.edu's message of 14 Dec 90 23:44:49 GMT In article <4e997ec6.1bc5b@pisa.ifs.umich.edu> rees@pisa.ifs.umich.edu (Jim Rees) writes: Domain/OS has a pair of processes, the purifiers (pids 3 & 4), that progressively write dirty objects to disk. I think they only write pages from unlocked objects. So the combination of the purifiers and sync should be sufficient. This is interesting. I have always wondered what those first ten processes are there for: USER PID SZ RSS TTY STAT TIME COMMAND root 1 6144 808 ? S < 0:05 /etc/init root 2 0 0 ? R 1366:11 null root 3 0 0 ? S 0:00 purifier root 4 0 0 ? S 0:00 purifier root 5 0 0 ? S 3:39 unwired_dxm root 6 0 0 ? S 0:00 pinger root 7 0 0 ? S 4:41 netreceive root 8 0 0 ? S 0:08 netpaging root 9 0 0 ? S 0:05 wired_dxm root 10 0 0 ? S 0:21 netrequest I understand #1 and #2, of course (init even has a man page), and now Jim has explained #3 and #4. Could anybody explain the remainder? No, I don't think I need to know. Just being curious, that's all. - Harald Hanche-Olsen Division of Mathematical Sciences The Norwegian Institute of Technology N-7034 Trondheim, NORWAY
