Hi guys, I have a kit pvp server called PvpFest. It has an obvious RAM leak and I can't seem to figure it out. It's not awful, but the server does require restarts often not to lag because of the leak. The server player count is almost always 150/150 The server has 4GB RAM The server has these plugins: AutoMessage, BuyCraft, CleanChat, ClearLag, CombatTag, Creeperheal, CustomCommands, Essentials, EssentialsChat, EssentialsProtect, EssentialsSpawn, GAListener, Hidestream, LinksonSigns, HealthBars (Custom), NocheatPlus, PermissionsEx, PvpTimer, Pwnfilter, RankMarket, SecretPotions, TimTheEnchanter, Vault, Votifier, WhatisIt, WorldBorder, Booscooldowns, Floauction, Worledit, and Worldguard These plugins could not be the issue because they were installed after the ongoing RAM leak: HealthBars, GAListener, CustomCommads, FloAuction You might be thinking that 4 GB RAM is too little for 150 players, but I am pretty sure that's not the issue. The server has this RAM leak no matter how many players are on, and the server has basically NO intensive activity. Everyone is in a small glass dome loading the same chunks, no one can break blocks, there's no liquid flow or block physics due to the type of server, and there's never more than 200 mobs or entities. Basically this is what happens: After a restart (with 150 on), the server looks somewhat like this: 4000MB Max 750MB Allocated 300MB Free After about an hour... 4000MB Max 2500 Allocated 1400 Free And the free amount will drain 100MB per second then get moved back up to about 1.5GB due to the garbage collector, this is the only server I have that's RAM numbers change so quickly. So after about 6 hours: 4000MB Max 4000MB Allocated 300MB Free And that's where it starts lagging and needs a restart, it's quite upsetting. I would really appreciate it if someone could help me figure out this RAM leak, thanks.
