Can someone please explain this one to me?
Where I come from memory leaks result in using more memory.
Then again in some parts of the world things falling to the ground cause gravity and Flying Spagetti Monsters rule.

Servers use a lot of memory, if there's a memory leak and it goes over the maximum limit, the server crashes, and so all the systems on that node go pop.

I'm sorry but that does not explain things very well.
Least not to me.
I get that the server uses a lot of memory.
I get that memory leaks cause the server to use more memory over time until there is none left and things crash.
I don't get how using lots results in a leak.
usually it's a leak that results in the system using alot.

You wouldn't say that a leak in a bucket was the result of the bucket being empty.
Is this some sort of logical typo? Or is there some sort of crazy interaction where using lots of memory causes a leak? That would just be odd if it was the case.

I would think so.

Memory leaks are caused by bugs in the code. Creating objects/variables and never releasing them. They remain in memory and the space is never released to be used again. When this is repeated over and over the memory useage grows, and eventally takes up so much space the server has no memory left to operate. Crash, bang, server goes pop.

And only normally happens if you are very sloppy with your programming, or the compiler/language/interpreter is bugged. My money is on the first possibility as evidenced by previous occurences in eve.

Go troll another forum area/thread. This isn't helping the OP in anyway.
Oh, and I'd like to see you code a game as complex as EVE, client AND backend.

It's misworded, leak is causing huge amounts of memory being allocated and crashing everything when it runs out of available mem.

memory leaks are pretty much what the earlier poster noted. An program reserves a specific area or amount of memory and then does not properly release it. Then the program reserves another area of memory for the same (or similar) purpose. A large number of professional applications have known memory leaks although they performance of the application is usually not affected because most apps are shutdown and restarted fairly often.
Taking a shot at the programmers for memory leaks is pretty classless given that very skilled and professional programmers occasionally have memory leaks in their apps, some obviously are bigger than others. Probably close to half of the reasonable sized applications on your computer can have memory leaks although they are not always readily apparent. MS Excel, Word, Adobe Acrobat, Windows 98 and earlier all have / had memory leaks in certain situations. Its just not as obvious as eves because of the 23/7 environment and the number of users doing things repetitively.
Unfortunately for CCP and the rest of the Eve userbase it seems that eve has a memory leak in some common areas of the program that are dramatically affecting the server performance.
As an aside the "LAG" that we experience in game can cause server resources to remain allocated for extended periods of time, thus causing further lag. It is one of those slippery slope analogies. Particularly for the database side of things, once things start timing out you often get memory leaks and sometimes, particularly if you are using someone elses database code, you cannnot do a whole lot to fix it after it happens. As the saying goes... Lag happens.
