Ciao,
we have a problem with network render.
We have 4 nodes, but after 1st right-completed render, the 2nd job in queue freezes.
This seems to happen with file resolution > than 3500 pixels (horizontal).
I post the log of manager and nodes.

PC:
1) name: PA025 runs manager + monitor + node and it is the machine where project is created and saved. (os: Vista x64)
2) name: PA023 runs node (os: XP x64)
3) name: RENDER02 runs node (os: Win server 2008 R2 ent. x64)
4) name: RENDER01 runs node (os: Win server 2008 R2 ent. x64)
Network paths are by "mapped network drive", so every machine links to PA025 as X:\ without problems.
Network policies and permissions are tested and ok.
Computers are recently formatted, so "no ghosts" of previous installations or dirty window register.
Computers have 16 GB of ram installed.


Manager (on PA025):

Render node: RENDER01: file_dependency_sent: da cancellare1.mxs
Merging process finished successfully!

**merged MXI of "Job 0" is saved in png and it's all ok, but after this "Job 1" does not start
The strange thing is that manager sends mxs file of "Job 1" (da cancellare1.mxs) only to a node BEFORE finishing merging process

** in RENDER01 and 02 there's the error: "Error in MXI sending socket. Code: Network operation timed out"
But file is sent in the right way after a second "MXI sent to the manager successfully!", so it seems all ok.

So, after 1st render all nodes freeze in "New job order received" status.
In Network monitor "Job 1" is tagged as running, and nodes are rendering, but S.L. remains at "0", also after hours.
We tested that this is not scene-complexity-depending.
During weekend we tested 10 queued coop renders (scenes were a plane+sphere, plane+cube, plane+sphere, and so on...) :
6 jobs with "x" size = 2200
2 jobs with "x" size = 3500
2 jobs with "x" size = 1000
"y" size was proportional, ratio 1,33.

7 jobs finished successfully.
Render nr 8 did not start, beacause was the "second big one".
Monday morning all nodes were in "New job order received" status, but still S.L. 0.


Any hints?
thank you
ciao
Luca
