> cdda2wav does not panic this system under these conditions: This issue has been discussed to death several times; it relates to a bad interaction between the I/O system and SYSV shared memory, where pages out of the shared region are still busy when cdda2wav exits. This appeared with the CAM integration, and *may* be related to the way the two interact. > 1) with the -N option (does not write data to disk) > 2) with the -n 1 option (reads/writes a single sector at a time, default is 55) > 3) when 'audio.wav' is a fifo, but it fails in a different (non-panic'y) way: > ... > No overlap sampling active > samplefiles size total will be 415316600 bytes. 10 tracks > recording seconds stereo with 16 bits @ Hz ->'audio'... > cannot set realtime scheduling policy: Function not implemented > cannot set realtime scheduling policy: Function not implemented > write(audio, 0x3004800C, 129360) = 8192 > Probably disk space exhausted: Undefined error: 0 This is a bug in cdda2wav it would appear; a short write is not an error. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
