Rendering Audio Track

Is this a bug because I was trying to reanimated a scene In Tpot 2 but I did not trim the audio I imported the entire thing make it play at 3100000th Millisecond the animator seems to run good at rendering the frames but when creating an audio track it crashes the site what I did I did before with an audio size 13.8MB played it at a certain Millisecond and still work fine so what makes the site crash.

i tried doing it again and it work well i played it during the audio track was being made and it came out good
