I'm currently running "ktrace sum /path/to/file/with/problem" here but that will create a ktrace.out of roughly 8GB since the error always occurs about 7.5 to 8 GB from the start of the file. Sending you 8GB doesn't seem very convenient. Would it be sufficient for you to run a kdump and mail you the first lines (up to the point where it's reading in a loop) and the last lines (including several iterations of the loop)? > DES > -- > Dag-Erling Smørgrav - des@ofug.org Regards, Paul Schenkeveld
