Really nice post in regards to info provided initially. It's rare to see that these days.
The weird thing in your screen shots that I see, is that in your Output Module Settings, the audio bit-depth settings seem to be grayed out for some reason. Are you using some sort of audio hardware that is customized, or perhaps some compressed audio in your project? Here's what I mean:
Thoughts? Aside from that, your project does sound as if it is pretty intensive, so I'm sure the problem could be occuring elsewhere...
Thanks for the fast reply!
Not sure why the audio bit-depth settings are grayed out -- perhaps it's because my render is set to output using the AAC Audio Codec -- when I have that selected, I notice that the audio bit-depth settings are grayed out, so perhaps that's why nothing shows up there.
The audio that's currently in my project are AIFF files, encoded at 44.100 kHz/32 bit U/Stereo. They've been in the project for a long time, and I was using them back before my renders started to hang, so I'm not sure it's an audio issue.
But I'll try rendering overnight with the audio output deselected, to see if that helps at all.
Would it help if I purchased more RAM and installed it in my machine? Or set the preferences up to render multiple frames simultaneously?
I think I solved my problem with this, not sure if it will also solve yours - even though this post is about a year out of date.
In system preferences on my Mac - I had put hard disks to sleep whenever possible. Since my OS is running on hard-drive 1 ( after effects, cashes, etc ) and my files are being written to hard-drive 2, I believe this iw where my problem lied.
I hope this helps at all.
I have been having the same error it doen't seem to happen with small projects tho..
If you reselect the output drive and folder it can fix this. It may be that the drive was parked/busy/sleeping/trimming at the exact time you hit render and it lost the path. It will not find it again until you reselect it from the Drive letter down (I found on: Z820, 2xSamsung 840 Pro in RAID 0, W7Pro, CC,).
Perhaps the likelihood of the drive being busy/fragmented is higher with bigger projects?
I think this may also happen with preference files sometimes.
