[Openexr-devel] File locking in Renderman OpenEXR display driver

[Casey Vanover]

Hey, guys.  I was wondering if anyone has had to deal with this.  I'm 
using the OpenEXR display driver in Renderman and I'm having some 
"hanging" issues.  From what I can tell, the driver is dying on the line:

_file = new OutputFile(filename, header);

and, it seems that the issue is that OpenEXR or some other agent is 
trying to lock the file before writing to it.  As the file I'm writing 
to is over NFS, the lock fails and the program hangs.  Has anyone else 
run into this?  And, if so, did you find a fix.  At the very least, I 
can render to a local file and copy that over NFS, but I was hoping 
someone had a more elegant solution.

Pertinent Info:
Renderman 11.5
OpenEXR 1.0.6


Thanks,

Casey
