Very high loads

I did some Google searches on this but only saw sometone talking about bad serial cables causing this. Could bad SCSI cables also exhibit this behavior in OpenBSD?

My top looks like this:

This is quite a high load for this server. But its not really running a lot of processes.

I did a vmstat 5 3 and got this:

 procs   memory     page                    disks         faults   cpu

  r b w avm fre flt re pi po fr sr w0 s0 s1 s2 in sy cs us sy id   124 0487296357656 1338 176 38 0 0 0 18 1 11 23 539 2610 213 7 10 83   017 0437700359244 426 46 26 0 0 0 14 1 0 30 455 2715 173 10 7 83   015 0410804359192 582 67 42 0 0 0 16 0 0 24 405 1325 116 4 6 90

Im not sure if these are normal values or not?

My drives are:

dev/wd0a on / type ffs (local)
/dev/sd0d on /var type ffs (local, nodev, nosuid)
/dev/sd1e on /var/log type ffs (local, nodev, noexec)
/dev/sd3a on /var/mail type ffs (local, nodev, noexec)
/dev/sd1d on /var/spool type ffs (local, nodev, noexec)
/dev/wd0d on /var/tmp type ffs (local, noexec)
/dev/wd0f on /usr type ffs (local)
/dev/sd2a on /usr/people type ffs (local, nodev, nosuid)
server:/net/web on /net/web type nfs (nodev, noexec, v3, udp, timeo=100)

Anyone come across similar problems?
