 I checked the list of Active Tickets but didn't see a ticket describing
 this issue. My apologies if I missed it.

 HARDWARE ENVIRONMENT

 Chipset: Intel Mobile Express 4
 CPU: P9600
 Memory: 2x2GB DDR3

 SOFTWARE ENVIRONMENT

 Fedora 12 fresh install with the kernel and pulseaudio updated

 [planar3d at blueplanet ~]$ uname -a
 Linux blueplanet 2.6.31.6-162.fc12.x86_64 #1 SMP Fri Dec 4 00:06:26 EST
 2009 x86_64 x86_64 x86_64 GNU/Linux

 [planar3d at blueplanet ~]$ pulseaudio --version
 pulseaudio 0.9.21

 PROBLEM BEHAVIOR

 pulseaudio memory/heap usage steadily creeps from 6.5MB to 2.6GB and
 beyond over the span of 2-3 hours.

 pulseuadio -k kills the daemon. The daemon is automatically respawned and
 process repeats itself.

 While the following commands were run System Monitor 2.28.0 shows
 pusleaudio consuming 119.7MB of memory
