I also have this mem-leak bug with this config:

mail.vol:
volume posix-mail
  type storage/posix
  option directory /data/mail
end-volume

volume locks-mail
  type features/locks
  subvolumes posix-mail
end-volume

volume mail
  type performance/io-threads
  option thread-count 16
  subvolumes locks-mail
end-volume

volume server
  type protocol/server
  option transport-type tcp
  option auth.login.mail.allow user
  option auth.login.user.password passowrd
  subvolumes mail
end-volume


mail-client.vol:
volume remote1
  type protocol/client
  option transport-type tcp
  option remote-host mx01
  option remote-subvolume mail
  option username user
  option password password
end-volume

volume remote2
  type protocol/client
  option transport-type tcp
  option remote-host mx02
  option remote-subvolume mail
  option username user
  option password password
end-volume

volume remote3
  type protocol/client
  option transport-type tcp
  option remote-host mx03
  option remote-subvolume mail
  option username user
  option password password
end-volume

volume mirror0
  type cluster/afr
  subvolumes remote1 remote2 remote3
end-volume

volume wb
  type performance/write-behind
  option aggregate-size 128KB
  option window-size 1MB
  subvolumes mirror0
end-volume

volume ioc
  type performance/io-cache
  option cache-size 256MB
  subvolumes wb
end-volume

We run Postfix Mail-Spool with Maildir Support on it, Courier-POP3/IMAP
as MUA.

After one week of operation, glusterfs uses about 1GB of RAM.
