I made all my textures "fit" but now i cant comply my map

every time i tried to comply it always had an error (after like 20-30 minutes of complying) .. the most recent 1 is this from the .err file :
hlrad: Error: Memory allocation failure
Description: The program failled to allocate a block of memory.
Howto Fix: Likely causes are (in order of likeliness) : the partition holding the swapfile is full; swapfile size is smaller than required; memory fragmentation; heap corruption
now i don't understand this but i tried to check the map for errors in hammer but it didn't find anything ... so i tried deleting some things that i thought mite cause the problem and it still had that error

so if some1 knows what my problem is then pls reply
