I am running spigot 389 and latest dev build (335) of multiverse inventories, and these other plugins: CoreProtect 1.74, CreativeGates 1.3.5, Essentials Dev2.9.703, EssentialsAntiBuild Dev2.9.703, EssentialsChat Dev2.9.703, EssentialsSpawn Dev2.9.703, Factions 1.8.0, GroupManager 2.0 (Dev2.9.703) (Phoenix), InventoryCleaner 1.0, LWC 4.3.1 (b811-git-MANUAL) (January 13, 2013), MultiWorld 4.4.1, Multiverse-Core 2.5-b648, Multiverse-Downloader 1.0-SNAPSHOT-b1, Multiverse-Inventories 2.5-b335, NoCheatPlus 3.8.7-beta-b294, Orebfuscator 1.8.3, Permissions 3.1.6, PlotMe 0.10b, PluginManager 1.0.2, PotionCraft 1.1.1, ProtocolLib 1.8.4-SNAPSHOT, SurvivalGames B 0.4.11, Vault 1.2.22-b277, WorldEdit 1-c7cc1de, WorldGuard 747-e3dfc6a

Running without multiverse-inventories works (for days). Running With crashes as often as 4-7 times a day. :-(

Your server ran out of memory, as you may expect Multiverse-Inventories needs quite a bit of RAM to operate, that being said it could also be a leak on our part. Give me some time, I'll look into it.

Im getting this error when People have stuff like herobrine's Axe in the Inventory. The "lore" string seems to "multiply" and the json's ends up being as big as 1.2 gigabyte!! - this seems to take too long to flush to disk, so either mvinv runs out of memory or the server "crashes"... Plenty of RAM free on the system, but if it suddenly needs a couple of gigs to Write the Inventory files heap might struggel :-/

Experienced the same issue this weekend - server started crashing 4+ times a day. Always shortly after a player died. Examined my MultiverseInventory json files and found 2 that were over 90MB. In my case the display-name had the repetitive "\u2019\u2020\u2019ÃÆ\u2019Ã\u2020\" text in it. I believe that's coming from CrackShot - a guns mod that I have installed on my server. Cleaned out all the extra junk in those 2 files (thank you UltraEdit for handling large files) and updated MV plugins and Crackshot. Will keep an eye on those files to see if any start growing out of control.

Happened again this weekend. Several json files had repetitive text. I see multiple tickets on this issue (colored lore corrupting). I'm updating to the latest snapshot again, but don't see any fix listed in these tickets

Sorry for late update... After the "latest" move to json only and other updates I haven't seen the issue
