Comment(by matth45):

 I notice that if I start jackd with a larger period (eg. 4096) as:

 {{{
 /usr/bin/jackd -v -R -p128 -dalsa -dhw:0 -r48000 -p4096 -n2 -P -S -o2
 }}}

 I do not get disconnects. (I do get higher latency). I also get the
 following messages repeated as long as a client is connected to the
 pulseaudio daemon:
 {{{
 D: memblock.c: Memory block too large for pool: 98304 > 65536
 D: memblock.c: Memory block too large for pool: 98304 > 65536
 D: memblock.c: Memory block too large for pool: 98304 > 65536
 D: memblock.c: Memory block too large for pool: 98304 > 65536
 }}}

 When I attempt to set shm-size-bytes in daemon.conf much larger that
 1024*1024*64 pulseaudio fails to start with the message:

 {{{
 E: shm.c: Assertion 'size <= ((pa_align(1024*1024*64)))' failed at
 pulsecore/shm.c:93, function pa_shm_create_rw(). Aborting.
 Aborted
 }}}

 A period of even 2048 still causes the frequent disconnects as seen above.
