Warning Leaf Cover 6, Data Not Found

[m1dude]

I am getting an error currently on my server that reads like this: 

23.10 20:27:11 [Server] WARNING Leaf cover_6 not found.
23.10 20:27:10 [Server] WARNING Leaf data not found.
23.10 20:27:10 [Server] WARNING Leaf cover_6 not found.
23.10 20:27:10 [Server] WARNING Leaf data not found.
23.10 20:27:10 [Server] WARNING Leaf cover_6 not found.

This continues on and on, and I am sure it is the source of lag on my server.  I have tried downloading the server log files, but the lines do not show up on there.  I have no idea what mods are causing this error either.  I know this is very vague but I need help if anyone is willing to give it.  The server has over 140 mods on it so it could be any one of these.  Has anyone else ever had this error and can help me with it?

It is very unlikely that this is causing lag for you:

2014-10-19 14:36:58 [WARNING] [Waila] Leaf data not found.
2014-10-19 14:36:58 [WARNING] [Waila] Leaf cover_6 not found.

That is from your ForgeModLoader-server-0.log file. Waila is generating the message. There must be some oddness in one of the mods that generates leaves or some oddness in the way that Waila is detecting/monitoring things. This shouldn't cause any lag and I see none on my server with a similar number of mods while getting this message. If you aren't doing anything server-specific with Waila it is safe to remove it from your server mods folder.
