This is using version 1.2.1. The shake translater is custom, while
the prman one is ILM's published display driver (with minor changes).
We are catching all exceptions, and in this case it is an Iex::EioExc
exception initially caught by Imf::OutputFile::writePixels(). Ultimately
I think it is being thrown by Imf::StdOFStream::write(), although it may
be in one of the other routines which does a seek.
Would modifying the ofstream's buffer settings to alleviate this kind
of problem? Or would doing
ios::sync_with_stdio(false);
help at all?
Thanks.

Are you using a custom node and catching the exceptions? If so, do
you know what they are?
We've had some intermittent seek problems here with both our own code
and the publicly posted one when rendering heavy scenes on the farm.
What version are you using?

Hello, our OpenEXR renders both from shake and prman have been
experiencing "Input/output" errors. I tracked it down to an errno
error, implying that it is a hardware and/or network problem. But
renders to other file formats don't suffer from this. Has anybody
else noticed this? Any ideas on how to work around them?
Thanks.
