Render keeps failing in same place

I have found a solution online , 

1. try clearing aftereffect cache by pulging the memory b4 render

Navigate to Edit  > Purge > All Memory and Disk Cache.

2. There is secret menu inside AE

1. select After Effects.
2. Hold down Shift and select Preferences.
3. Choose General, and don’t let go of that Shift key!
4. When the Preferences window pops up, you will notice a Secret category available at the bottom. Open it. 
5. Try adjusting these options. You can Disable Layer Cache and Ignore Sequence Rendering Errors. 
6. Select OK then try to render again using the Render Queue or Media Encoder.

Well, you answered your own question: Yes, it's whatever is going on at that point in time in your comp. Start by checking your hardware acceleration options and such. Resource-hungry layers and effects suddenly kicking in are often the cause for crashing OpenGL or simply consuming so much RAM that rendering bombs out.
