The :vfs.lodirtybuffers sysctl is gone for some reason. Oh my. Maybe we have two problems here. Alfred had similar problems and the patch fixed it right up. Try running a 'top -S -s1' while you are running your test, with my patch but without doing the sysctl's, and tell me what the various programs block on when the problem occurs (buf_daemon and whatever program is causing the hicup). -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
