Unable to terminate workflow

[#1]

I have a scheduled workflow that runs every hour and takes around 2 minutes. Yesterday the workflow did not finish, still indicating "In Progress". The "Terminate This Workflow" link throws an error with correlation ID xxx.

How can this workflow be terminated???

[#2]

You might want to post some ULS logs here by tracking back using that correlation ID  to give some clue.

I agree with Chit. The ULS logs should give a more detailed error. If that doesn't work, the admins on the server may have to terminate it.
