Server seems to be crashing often

How can I find out what Plugin is crashing my server? Where do I look?
Someone please help?

The way to do it is unload all plugins, then add them one by one until the problem returns.

If you have a lot of plugins then you can do it quicker if you load half of them only, then half > half > half until you boil it down to the individual problem.

Thank You JimDeadlock
Anyone know what this means? Top

The RustEdit extension you have installed is erroring.

Do I need RustEdit on a non custom map?

Merged post

OK..Just checked RustEdit is not installed on my server.. I looked for the Oxide.Ext.RustEdit.dll in /serverroot/RustDedicated_Data/Managed folder and its not there.

Pretty sure that's what IOCore is from, but do you have any other extensions?

Somthing wrong with my host Wulf.... I just intalled RustEdit and still Cant find the Dll in the folder. All I have is RustEdit and Oxide installed. No custom map.

Sounds like they don't show you all of the files there.

Yea... But when I Click to uninstall RustEdit in TcAdmin And server restarts, I get that error.
