I do not know what that indicates. I've seen that problem
once earlier at #pulseaudio, and in that case everything
seemed fine. I'm not a shared memory expert, so for me
"everything" means the following (you can check these too):
/dev/shm is mounted as tmpfs and the permissions are correct
(i.e. the same as on my own machine):

drwxrwxrwt 3 root root 80 21.4. 05:40 /dev/shm

A workaround which should get your sound back is to
uncomment (the semicolon is a comment character!) the
disable-shm line in daemon.conf and set the value to "yes".
