[linux-audio-dev] shared memory question

[Dave Phillips]

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
:

  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 ?
