Quick question regarding dungeons in metin2

[TMP4 16380]

Hi,

 

When a dungeon is created, it get a map index * 10000 +x.

i mean someone play a dungeon and get this index: 3520000, the second player/group get 3520001 and so on until 3529999

The used indexes never get reused until a restart.

 

My question is the dungeons never will be destoryed and stay in the memory causing overloading in big servers?

Or they get cleaned just the indexes not used again until a fresh start? (If they get cleaned, when? When everyone logged out?)
