[please CC me since I'm not subscribed to the list] [Note: cross-posting to cdwrite and freebsd-questions lists] Hi all, I am using cdrdao to read and write CDs from/to my SCSI CD-R. As suggested in pkg-descr and pkg-message (FreeBSD ports system) I have set the following in my kernel configuration file: options SYSVSHM #SYSV-style shared memory options SYSVMSG #SYSV-style message queues options SYSVSEM #SYSV-style semaphores options P1003_1B #Posix P1003_1B real-time extensions options _KPOSIX_PRIORITY_SCHEDULING options _KPOSIX_VERSION=199309L However, I always see errors like the following: ERROR: Cannot create shared memory segment: Cannot allocate memory ERROR: Try to reduce the buffer count (option --buffers). According to cdrdao(1), the default number of buffers for FreeBSD is 20 (1 buffer == 1 second of audio data). Sometimes I can get cdrdao to work with --buffers 16, but now I'm also getting errors with this number of buffers. If I go lower (say --buffers 10, which is the minimum) I get buffer underruns. Single-user machine Pentium III 600 MHz, 768 MB RAM FreeBSD-4.3 (RELENG_4_3) I have X running but no KDE or Gnome ... just plain icewm. Errors occur even with low system usage (just X and one or two Eterms). Questions: i) why is cdrdao not able to get the memory it needs? There should be plenty of it most of the time. ii) Is there anything I can do to fix this? Change my kernel config and recompile? Play with sysctl? Thanks in advance for any help, Fernan PS: I'm using cdrdao basically because it's the only way to get cdparanoia-style ripping in FreeBSD. All other rippers are not just paranoid enough (even with discs that appear OK there are problems). PS2: cdparanoia builds on FreeBSD but is not able to open the CD-ROM (ATAPI in my case) or the CD-R (SCSI) for reading.
