Subject: [linux-audio-dev] shared memory question

Greetings LADders:

  I'm working with Kjetil's vstserver, testing various plugins, and
occasionally I get this error from the server :

        VSTSERVER/SMS_new: Unable to allocate 12288 bytes of shared memory.
        VSTSERVER/CH_new: Could not set up shared memory.

  The plugin then politely refuses to load. 'cat /proc/meminfo' reports
:

        total: used: free: shared: buffers: cached:
Mem: 526311424 511303680 15007744 0 70569984 234008576
Swap: 337195008 223801344 113393664
MemTotal: 513976 kB

MemShared: 0 kB

LowTotal: 513976 kB
LowFree: 14656 kB
SwapTotal: 329292 kB
SwapFree: 110736 kB

  I tried expanding the shared amount with 'echo some-big-number >
/proc/sys/kernel/shmmax' but still got the error. I'm obviously not
understanding something, so I turn to the wizards for help. Is there a
fix for this problem ?

Best regards,
