I have this problem on 7.2-S for pretty long time. But as I sendfile() very small file (several hundred bytes) from flash I was blaming faulty flash stick. I've even made a crontab entry to replace corrupted file. So the problem seems to be probabilistic, depending on amount of transferred data. -- Eugene Perevyazko _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
