Deleting Process Model uploaded for Analysis


i have uploaded the process models for Analysis which contains process id field of more than 100 chars. hence because of that when i tried to associate event maps with the process model, it got errored out and the Event map got disappeared from the unassociated and it was visible nowhere in the MWS page.

Now i need to delete the those process models and the event maps.
But when i try to delete the process models the server is getting hanged and i need to restart the server.
The issue here is i have to create process models with the same name again and upload them to IS.

Any suggestions or workaround would be of great help for me.

Thank You,
