We have one, which seems to have been stable for about 2 weeks now. Our machine crashed regularly after staying up for about 2 - 4 days, but now it has broken the uptime record by doubling the last value (a week, made in a holiday season): # uptime 1:11pm up 14 days, 3:31, 55 users, load average: 3.73, 3.22, 2.67 # How did we reach this? Simple, just configure the kernel parameters NBLK4096 & NBLK2048 from 2 to 16.... How did we know which parameters to change? Simple, our hardware maintenance was in contact with Mips (UK) more than our local distributor... We have now found a few more interesting features, which can be seen only when the machine runs long enough. Talkd and in.phoned both seem to be hanging around in process table, so I have now killed about 50 of each. Our /etc/passwd now contains 1760 lines and 600 - 700 of our users visit the machine daily. Average simultaneous users has been as high as 96, but now seems to be around 60 - 70 at maximum. We are still running RiscOS 4.51, but as soon as 4.52 comes here, we try to get it. We heard that these diskquota-panics have been somewhat cleaned in the new version. We have had plenty of them... The machine was installed last year. If you have any questions I will try to answer. - at -- Anssi Toivo - TUT Computer Centre - at@cc.tut.fi
