I have a Minecraft Magma server and sometimes I get this error message:
[18:58:13] [Server thread / WARN] [net.minecraft.world.storage.SaveHandler]: Failed to save player data for player name
At that moment you can't craft anything until you restart the server. And then mostly things are missing in the inventory. Do you know why that could be? I have enough memory and enough RAM. The CPU is also not busy.
Moin, to be more precise, you should upload the latest.log at pastebin or hastebin and link it here. Just with your information, I would guess that there's not enough RAM or too little storage space.
There are some potentially relevant warnings like these:
found FMLCorePluginContainsFMLMod marker in OpenModsLib-1.12.2-0.12.2.jar. This is not recommended, @Mods should be in a separate jar from the coremod.
The coremod openmods.core.OpenModsCorePlugin does not have a MCVersion annotation, it may cause issues with this version of Minecraft

I couldn't find Mwhr, but the problem will be with one of the mods.
