glusterFS (v3.0.3) memory leaks?

Hi -

I am about to migrate to GlusterFS but I'm experiencing some possible 
memory leaks I'd like to get rid of before. This seems to be the same 
problem as reported before by Larry Bates:
http://gluster.org/pipermail/gluster-users/2009-December/003639.html

Setup is composed of a couple of GlusterFS v3.0.3 servers in RAID-1, 
running both on Debian/Lenny.

Config files were generated with the following options:
~# glusterfs-volgen --name store1 --raid 1 gl1:/export/nunki 
gl2:/export/nunki

It's quite easy to repeat the problem just issuing an "ls -lR" on the 
client: glusterfs memory usage slowly increases (it needs less than 30 
minutes to acquire the whole RAM available before swap is in action):

Mem:   8193660k total,  8143884k used,    49776k free,    97156k buffers
Swap:  7815580k total,  2063112k used,  5752468k free,   726764k cached

   PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND 

30245 root      20   0 7564m 5.3g 1116 S    1 68.4   1:06.66 glusterfs 
 
 


Removing all optimization translators does not really fix the problem 
although the memory usage is growing significantly slower.

I also tried echoing 3 to /proc/sys/vm/drop_caches as suggested by 
Raghavendra G. ealier, with no effect at all.

Any thoughts?

Thanks in anticipation,
