Fatal error in gc, Too many heap sections upgrading to Unity 5.5

Trying to upgrade my project to Unity 5.5 and getting a bunch of these popping up when re-importing assets.

Any clue what might cause it? Never seen it before?

Hey, it sounds like there’s not enough ram on your machine to update a huge project, but we would need a bug report and repo project to fully dig into this! Would you mind sending one in?

Also, a quick test to do is to not run any virus scanners in the background to see if that’s causing the issue.

Hi, Thanks for the reply. I have 32gb of ram so it’s a bit surprising if it is running out of ram.

I kept clicking ok after each error and managed to open my project after about 5 or 6 errors but my project had some issues with assets and now crashes when I a try to open it, not sure if it’s related to these errors or not.

If i can build a repro I’ll send it in but my project is too big to send as it is.

Yeah, the best would be if you could strip down the project, read a bit more on how to do that here.

Also, let me know if you tried turning off virus scanners and if it solves the issue!
