SW2010 Crashing during PDM Workgroup Check-in

Here in the office, we have noticed that ever since we have upgraded to 2010 (currently running SP2.0) and we attempt to check-in large assemblies into our vault we often crash.

The crash does not occur when SW is running a query of all the files and drawings but at the step where it is running through each file and checking them in. For example, it may take me 3-4 attempts to fully check in a large assembly and after each attempt a higher % of files is up-to-date with the PDM files.

There are 3 of us here in the office and 2 of us have noticed these reoccuring crashes. I should note that the 3rd person has not been working on large assemblies that much since we have upgraded to 2010.

Is this happening elsewhere? ideas?
