Or the update daemon, from the man page: The update daemon flushes the filesystem buffers at a regĀ ular interval. It has two modes of operation. By default it will wake up every 5 seconds and flush some dirty buffers. If this is not possible, it will automatically fall back to the traditional behavior of waking up every 30 seconds to call sync(2). -- Brian --------------------------------------------------------------------- Mechanical Engineering [EMAIL PROTECTED] Purdue University http://www.ecn.purdue.edu/~servis ---------------------------------------------------------------------
