Eagerly waiting... :) What happens with Sybase: data and transaction logs dumps are handled by a dedicated backup server process. The backup server handles getting data from the database and then passes the data via a pipe to a subprocess (an exec()'d program) that does the actual i/o to the disk or tape. The link between the backup server and this i/o subprocess fails. I have some ktrace output, but I'm not sure how reliable it is since the i/o process behaves differently when traced than when not traced. -john To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
