Alain,
Today, there are not high I/O loads. This server was intended to
replace two older HP-UX servers. I had just begun to migrate the
workload to the new server when the crashes began to occur. There are
some minor, sporadic I/O loads but nothing that I would think could
trigger the bug discussed in your link. However, I haven't measured the
workload closely yet, so there could be spikes.
Best Regards,
