Memory leak of the glusterfs client process?
What type of volume (`gluster volume info`) are you using and how many 
clients are accessing the volume? Can you share the client(s) and the 
bricks logs when you see the ESTALE error? Also share successive state 
dump outputs of the process where you suspect dict_t leaks.
