Memory Leaks

 

[Dr Super Good]

Wikipedia describes memory leaks quite well.

In the case of Warcraft III there are both memory leaks and resource leaks. The memory leaks generally are only a problem for older computer systems with very limited memory. Modern computer systems allow Warcraft III to use so much memory it would take an absurd number of leaks to run out of virtual memory address space, by which time a map session has almost certainly ended. Internal resource leaks though are still a huge problem, and can cause performance to degrade to unplayable levels or even crash Warcraft III. To some extent both go hand in hand, however people mainly fix leaks due to resource leakage rather than memory leakage.

In case you have tons of triggers I would not really bother to go through each single one.

1. Read basics tutorial of how preventing: UnitGroups-, PlayerGroups-, Points-, Effects- leaks
2. Create an extra variable for each of named types above (sometimes "Points" needs 2, but you would see)
3. Scan all triggers which run very often during the game session (very often is something like each second or so, mostly important for periodic triggers)
4. And remove all your leaks from these those triggers and just forget the rest.

It can be a pain to go through really all triggers, also triggers that run only once, or so, but the realistic benefit probably won't be even mentionable.
