I'd be interested to see the output of top here, whilst xv is running. A quick question: when you say 'freezed' what do you mean? a) Totally hung - no response from the machine AT ALL (includes inability to reach it across the network). b) Partially hung - machine is still doing 'something' (disks working/clock if visible is still ticking, etc) c) Not hung - top shows xv using all CPU for a long time, but other processes continue to run, although very slowly. Also, d) What size images are you trying to use (in k or M) e) Does xv start at all, or just 'freeze' the system immediately? -- Regards | _/\_/\ Andrew Johns BSc (Comp Sci) | / \ TurnAround Solutions Pty Ltd | \_...__/ http://www.turnaround.com.au/ | \/ "The box said 'Requires Windows 98, NT, Linux or better' so I installed FreeBSD."
