After Effects 24.5 fills RAM with preview and then has to be killed

I have a new Project. I import a 20 min 360VR video sequence, and drag it into the interface to create a new composition. 

 

After a few seconds, After Effects starts caching the frames into RAM (A green line above the composition timeline.) I can see the RAM usage go up and up very quickly.

 

And will simply keep filling up RAM memory with the cached frames until After Effects errors out. 

 

I can turn this off in each individual composition by going to Composition>Preview and unticking "Cache frames when idle"

 

First. After Effects should not be filling the memory with cached frames. A bit of memory sure. But NOT the whole thing. Especially since I have a nice speedy SSD that I've pointed the cache folders at.

 

Second. There is no option to turn off the Cache Frames when Idle for new compositions. ESPECIALLY given this huge problem that should be an option.

 

I have been trying to find if there is any way of limiting the RAM cache. Either when previewing, or caching frames. But I cannot find any way to limit the RAM used.

 

This seems like a serious bug or very bad decision, given that so far After Effects will fill my RAM with cached or previewed images, unless I specifically turn something off.

 

Please fix this. Cached data should NEVER, NEVER fill the RAM to the point that the application can no longer work.

 

Windows 10 - 22H2

32GB RAM

i7 - 7700K @ 4.2GHz

M2 SSD for OS

MS SSD for cache

RAID 5 HDD array for clip storage

Have you tried with AE 25.0.1 to see if the issue still occurs?

Cache Frames When Idle isn't a per comp setting. It's an app wide preference. So as long as it is turned off, it won't turn it back on for new compositions. If you're seeing that, then I'd suggest resetting your preferences to make sure nothing has been corrupt. 

 

That you're running into AE erroring out due to Caches Frames When Idle being on sounds like a memory leak we don't know about. When you import the 360 video, is that using any particulars codecs or plugins? Are you able to capture a log (Help -> Enable Logging, Repro bug, Help -> Reveal Loggings files, file "After Effects Log.txt") and post it back here? That might help us understand what is happening and how to help.
