I've a simple AFR configure, two server, two client.
if I do copy of 10G file, glusterfs client process grows and grows , > 5Go
however I just define

 volume io-cache
type performance/io-cache
option cache-size 2048MB             # default is 32MB
option page-size  128KB             #128KB is default option
option cache-timeout 2  # default is 1
subvolumes iothreads

so it is glibc problem or a memory leak ?
memory does not scale down.
