Nobody can tell you anything without exact system info or other technical details like exact comp and render settings. It's of course possible that you simply exhaust the resources of your computer, but then again this might be something simple in your settings just as well.
Late 2015 iMac 27inch Retina, 3.3Ghz i5, 32GB RAM, AMD Radeon R9 M395X 4096MB. Running in After Effects CC 2017.
What were your render settings?
One was rendering to lossless, then I tried H.264, all at 1080 24p.
Are you rendering via the render queue in AE or via the Adobe Media Encoder?
What, exact, versions of the software are you using?
