Re: Potential Memory Leak?

Hi Karl,

Your glusterfsd config is simple with only 4 translators.

Is the problem seen every time you run your script?

Can you run the script using a simpler client config file? just
connect the client to a single server (no afr/unify etc on the
client side)

just have the folloing in your client spec and see if the glusterfsd
memory grows:

---

volume sxx04
 type protocol/client
 option transport-type tcp/client
 option remote-host sxx04b
 option remote-subvolume brick
end-volume

----
