Ensel, I chatted with Scott a day or two ago, and he told me he believes he has tracked down a bug in the adaptec device driver under high I/O load, and thinks it is possible that quotas are triggering slightly higher load resulting in the bug being exercised. He has a patch, which hopefully he has now sent to you? Robert N M Watson Computer Laboratory University of Cambridge
