leak in hull 0 but there's no leak

I work on my map 2 months, and have succesful compiling at least 50 times...
when I was finishing my map (putting teleports) and start compile proces, errors showed up. leak in hull 0 and acording to coordinates entity_light was eror...when I delete that, second error apear, and acording to coordinates, error was in stop timer...which is imposibble !!!
I don't know what to do...I put all my knowledge and effort in that bunnyhop map, and I don't want to lose it....pls help....
p.s. I try to put huge block around map, but max number of patches shows up :(

maybe some entity is connected with world (for example the wall is tied to func_wall, and the backside of it is out if map), or yes, use leakrmarker. But make sure after using it, copy the whole map in new .rmf and don't continue building it in .map file, cause when you use it again in future, then leakmarer may destroy all you work (as happened with me).

use the pointfile method of detecting the leak. always works for me!

TAKEN FROM FPS BANANA:

It's the best way to find a leak, we called it "Pointfile", the "Pointfile" method will generate a line where you can find the leak.

/!\WARNING/!\ : THIS METHOD WORK ONLY FOR HAMMER 3.5 IF YOU HAVE HAMMER 3.4 UPGRADE IT !

Open your map, select Map->Load Pointfile.
When he ask you to open the default pointfile called ".pts" say "No".
Open the file called ".lin".

QUESTION : WHY WE OPEN THE LIN AND NOT THE PTS.

The PTS file will show many lines, and it will be difficult to find your leak.
The LIN file will show only one line, and it will be easy to find your leak.

You will see in the 3D view the line, to find your leak : go inside your map, try to find the line and normally the line go throught the leak or he will point the entity outside of the map.

QUESTION : THERE ARE MANY COLORS ON THE LINE, WHAT DOES THEY MEAN ?
When the line is blue, you are far from the leak.
When the line is red, you are near from the leak.

QUESTION : I FOUND MY LEAK AND I FIXED IT, HOW I CAN DISABLE THE POINTFILE ?

Just do "Map->Unload Pointfile".
