Read the Doom wiki:
http://doomwiki.org/wiki/Static_limits#Visplanes

You should get Visplane Explorer if you're using DoomBuilder, it really helps visualize how visplane count is affected by things, and shows where the game can crash.

Personally I had a big visplane problem when I tried to make a detailed pentagram in my map, I thought it would be simple as technically it was two sectors and only two different textures, but the way Doom's renderer works, it was splitting it up into a ridiculous amount of visplanes, and I had to hide its ceiling half by changing it into F_SKY.
Picture related (pardon its size), it's said map in Chocorenderlimits, note the high amount of visplanes (PLN) onscreen despite the relatively simple scene. It's almost all in that pentagram.
