Thans for your mail.
I have tried to modify the "enable-shm" and "shm-size-bytes", but it seems
itdoesn't work. It also show that "Using shared memory pool with 1024 slots of
size 64.0 KiB each, total size is 64.0 MiB, maximum usable slot size is 65496".

Comment # 5 on bug 94316 from Tanu Kaskinen
The crash seems to happen when accessing memory pool memory, probably when that
happens for the first time. For some reason the operating system doesn't like
that. The problem probably goes away if you set "enable-shm = no" in
/etc/pulse/daemon.conf. If the system is very tight on memory, you could also
try playing with "shm-size-bytes" in daemon.conf to set it to some lower value
than the default, although my (limited) understanding is that lack of memory
shouldn't be the problem if the crash happens already on the first access to
the shared memory. If the system has memory overcommit disabled, allocating the
memory pool should fail in an earlier phase, and if overcommit is enabled, this
code shouldn't fail, because it only consumes the first 64 kB from the memory
pool, which surely can't cause the memory to run out (otherwise you'd have
bigger problems).
