Grasshopper Display Error

I keep getting the following messages:

"An exception was thrown inside the drawing pipeline:

Source: System.Drawing

Type: Exception of type 'System.OutOfMemoryExecption' was thrown.

The display of objects will be disabled to prevent this from happening again. Please save . . [yada yada yada]"

and

"An exception was thrown inside the drawing pipeline:

Object: Group

Source: mscorlib

Type: Exception of type 'System.OutOfMemoryExecption' was thrown.

The Grasshopper display routines have gone into ultra-paranoid mode in a last-ditch attempt to minimize damage. One or more objects will probably be drawn as blank rectangles with error message.

Display performance might be affected for this session."

Then grasshopper turns completely red and sometimes rhino crashes. I didn't change anything in the definition when this started happening. I was working on another file and when I returned to it I got the display error. I've been able to isolate the components causing the problem, I haven't fixed it yet, but I assume that I can work it out. I have various grasshopper plugins installed: geco, gHowl, DIVA, Local Code, and Hoop Snake. In the grasshopper definition that is generating the error, I'm only using geco, and all geco components are disabled when I get the error. I've never seen this before and I'm curious if anyone knows what is going on. I found a similar error in this post. Thanks.
