Hi, 

I'm using gluster3.4.alpha2 ( 3.4.alpha 3 failing at self-heal daemon) on debain wheezy 

Got lots of this from syslog: 

Apr 23 13:57:41 localhost GlusterFS[16976]: [2013-04-23 01:57:41.505530] C [mem-pool.c:497:mem_put] (-->/usr/lib/glusterfs/3.4.0alpha2/xlator/performance/io-cache.so(ioc_readv+0x3ab) [0x7f5090b2f34b] (-->/usr/lib/glusterfs/3.4. 
0alpha2/xlator/performance/io-cache.so(ioc_dispatch_requests+0x3a8) [0x7f5090b2ee88] (-->/usr/lib/glusterfs/3.4.0alpha2/xlator/performance/io-cache.so(ioc_frame_return+0x3c1) [0x7f5090b31c71]))) 0-mem-pool: mem_put called on fr 
eed ptr 0x1fbc874 of mem pool 0x1fbaa30 

and /usr/sbin/glusterfsd for that volume stop worknig 
how to debug and solve this problem? 

When running all seems to be fine.
