I don't know. Anyways , for 10 hours sytem here has percentage of system time as high as 80 percent. No idle time. The same time I can't find any resource consuming processes on the system. There about 17 users now logged in , and pstat shows ~11000 vnodes , while on the similar system under latest SNAP there are only ~9000 of them and ~25 users on-line. I suspect that the system moves now toword lockup because of something ... probably some deadlocks in the kernel and too many processes having to wait for the resource to be freed ? How can I trace the kernel ? Is there a way to find the reason for such behavior ? System has QUOTAs switched on 5 FS, this is P90/128Mb RAM Bustec SCSI 946C + 2 Barracudas ( 1Gb + 4 Gb). X11 is working as well ( but it has nothing to do with it , since when the system time jumped that high , X11 wasn't active). Just in case some guru will read this stuff , here comes the output from few commands: Oh , f****k ! The system time've just returned to it's usual value, as well as load average ! =-=-=-=-=-=-=--=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Sun Jun 18 11:37:24 EDT 1995 =-=-=-=-=-=-=--=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- =============== UPTIME ========================== 11:37AM up 2 days, 20 mins, 15 users, load averages: 0.08, 0.19, 0.69 =============== PS =========================== PID TT STAT TIME COMMAND 0 ??
