Workflow Error Monitor

Hi all,

I have a workflow that is actually working, but apparently is triggering more often than i expected and erroring out because users are still editiing when the 'update' is taking place.  I'll be workign on my workflow so this doesn't happen.

My question is this....

I have 300 'error instances in the monitor.  Is there a way to mass delete them (without building a webservice) or do i just have to delete them individually?

Do I even need to deltete them or will the purge off at some point?

Update: since 'fixing' the workflow the 'error' instances are actually clearing themselves up.  I assumed since the error monitor indicated that the wf was terminated that it would re-trigger.
