>From time to time (i.e., several times a day), a command started from csh
on our 5820 (DEC/RISC Ultrix 4.0) takes 15-30 seconds to start, regardless of
the load average of the machine. A "ps axl" on the controling terminal shows
it's actually the csh which is in disk wait, with funny flags (some digits
missing): in the following output it's the last line.

Any clues, help? It is rather annoying to have to wait 30 secs for an ls of
a directory on the local disk containing 4 files on a machine with load avg of
1.5 and presumed to work at 35 MIPS.
