Thanks. First step successful - I can steadily reproduce problem on

fine. If I preliminarily manually adjust queue depth of one disk -
everything works fine. I'll investigate it tomorrow.
Glad you have managed to dupliate it - the queue depth thing is
inetersting, what changes did you make ? I can try them here and see
if they improve the situation on either of my two machines.
For the record, queue-full is a common, expected condition in CAM. It's not
something that should be avoided =-)
Should we maybe have a counter in sysctl rather than flooding the
console with these messages then?
