[Gluster-devel] rpc problems when using syncops in callbacks

I am trying to use syncops in a custom
translator to keep my code at least borderline readable, but I am having
Using a syncop in a
regular fop is fine. However, in a callback it causes a 'freeze'
(synctask_yield called by the SYNCOP macro doesn't return).
What seems to be the Problem:
at the traces, there is no corresponding trace from rpc_clnt_reply_init
on the client to the trace from rpcsvc_submit_generic on the server. In
other words, the rpc reply gets sent but isn't correctly received. Obviously this is not really a networking problem but something else... I'd guess it's a deadlock somewhere on the client?
the point of the syncop call onwards the client doesn't 'get' any rpc
replies any more (the next GlusterFS Handshake sent by the client, which
is received by the server and replied to, leads to a disconnection
Again: This problem is only
occurring when calling a syncop from a callback function inside my
translator, if I call the same syncop in a fop call it completes fine.
I hope you can make sense out of the above problem description.
Thanks for your time ~
