serious rendering issues.
AE is crapping out after rendering three seconds of this comp. There are a lot of layers but not a ton of effects. I’ve precomped everything that I could. I’ve rendered out heavier compositions in the past.
Currently, I have it set to flush the memory every ten frames. I did have it at 15.
Anything else I can do to optimize this render?

is it crapping out at the same frame every time? if so, it may be an effect issue, look for an effect or layer with an effect that starts at the point where the render crashes. hide that layer or hide the effeect and see if it renders further.
if it does, then you may need to find a work around. sometimes moving the effect to an adjustment layer may help (or , if it is already and adjustment layer, apply it directly to the layers). you may also be able to precomp that layer and prerender it out by itself. sometimes you just need to create the effect in a different way or live without it.
sometimes just rebooting helps… you might try that one first.

This has no relevance to your question, but I am excited by the idea that I can flush frames the way you mention – how is that done?

hold the shift key while choosing preferences>general (actually it can be any prefernce). then from the preference window, click the pref pulldown and at the bottom will be one called ‘secret’
choose it and there are a couple choices, the onw you want is the purge frames interval. just set the point that you want ae to purge frames.
usually you would only use this if a render kept crashing and you suspected that the crashes were due to ae not clearing the ram cache properly. a tell tail sign is if you notice that ae is crashing when the ram value (as seen at the top of the render queue) hits the max ram cache setting in the memory&cache settings (default is 60%).
so, when ae crashes look at the ram value in the render queue, if it is at the max ram cache setting (like 60%), then ae is probably having prblems clearing the cache and setting the ‘purge every xx frames’ value to a value less than the frame that it crashed at may help. note that forcing ae to purge frames at regular intervals will usually slow down your rendering.
so, for example: your render crashes after hitting the 60% ram mark at frame 120, try using the secret pref to set the purge frames to 100.
another good thing to try (probably before using the secret pref) is to choose edit>purge>all prior to rendering. this will make sure that the ram cache is cleared prior to the render and often helps.

Thanks for the advice. It seems like I might have been having a bit of trouble with a time warp effect.
I also just shut the system down for an hour and came back. It rendered the rest out fine.
