"An internal error occurred"...

I have several plugins that are VITAL to my server, but recently I have been receiving "Internal error occurred" responses when I go to enter various commands that usually if not always work. If there is any information I need to provide, I will be more than willing to comply. Thanks in advance for your help.

Server Info:
1. Linux (MineOS)
2. N/A
3. Linux box 2.6.33.3-tinycore #2012 SMP Wed May 12 17:05:42 EEST 2010 i686 GNU/Linux
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-tc_2010_01_30_13_43-b00)
OpenJDK Server VM (build 17.0-b08, mixed mode)
4. No wrappers

6.MineOS start button
7. Voxel suite, MultiVerse, MagicCarpet, WorldEdit, Essentials, DeathTP, and several minor ones.
8. Trying various commands, such as magiccarpet and world creation through MultiVerse. Returns "an internal error occured".
9. magiccarpet, worldwarp, and others

 

The information is in the post above yours (Not getting help, ...). Please fill that out because its very important.

 

I edited my post to meet the requirements, can you help now?

 

remove plugins one by one and look which is causing the error.

 

internal error is usually client-side, right? are you getting anything in the server log at those times?

 

I believe so, however the forum won't let me post the .log file. Workaround?

 

assuming the problem is that the log is too big, rename it, start the server, then post the much smaller resulting log
