Permission issues? Hmm, tell me more about your render node/file server
config:
1) What OS on the file server (Mac OSX 10.??, Linux, Netapp, etc)
2) What OS on the render nodes?
3) What file network system (NFS, SMB/CIFS, AFP, etc)
I've seen this problem appear with AE only where the issue is with
the file server, and not an AE problem. (AE just seems to be good
at exacerbating it). In particular with the file server is OSX
(specifically, Snow Leopard) with both NFS and Samba.
In the case of NFS, checking the system.log showed weird errors from,
IIRC, gssd, that lead to some kind of default behavior of stock OSX nfs
which tries to involve kerberos, and under very light load would fail,
causing random perm errors. If you have OSX as your file server, check
look in your system.log (and perhaps others in /var/log) for OS errors
around the time of the failures (use the 'Frames' report 'Start Time'
column to determine the approx time the frame ran and failed to correlate)
In the case of SMB, check your samba logs on the server for any weird errors
on or around the time of the failed render.
BTW, paste the complete frame log here showing the perm error
so we can see some context.
