: :Hello Matthew, : :here's s.t. I can reproduce on all machines: If you try to :read audio data from a CDROM using cdda2wav (latest version; :shipped with cdrecord-1.8a16) and the resulting audio file :is on an NFS, it will be 50k-100k too small. I tried this :with all flavors NFS v2/v3 TCP/UDP--the same. : :cdda2wav writing to a local FS works perfectly. Not that I :need to use it w/ NFS--it's a bad idea anyway--but it may :help to get NFS more stable. : : Bjoern Bjoern, ktrace the program run. I suspect the problem is not NFS but that the write() latency is causing one of cdda2wav's forked processes to exit and kill its child before the child finishes writing. ktrace -t cn -i cdda2wav .... kdump -R | less Try to match up reads from the CD to writes to the output file. See if the final couple of read/write's match up. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
