It works fine for my needs, I only get swap_pager: indefinite wait buffer: device: da0s1f, blkno: xxx, size: xxx when performing heavy operations, such as rsync of a 1 GB database dump file. All references to the problem I found point out hardware failure. Could, however, the problem be simply that the I/O does not manage to let the request go through within the 20 seconds wait time and that the hardware is OK (apart from the fact that I/O is slow? And - is this message just a notice, or does it mean that I get data corruption? Thanks, Iv
