we have a crm 2011 local installation , we were running fine with custom plugins that were sending sms's amongst others ... however after a deployment a couple of weeks ago ... we are encoutnering an issue. i have removed all waiting or pending workflows and have created a temp workflow that only changes the name of an entity and is run on demand on an entity. a very basic workflow for testing purposes. it however now crashes the async service completely. with no other workflows waiting to be run and im stumped as to the problem. here is the event log application error. any help would be greatly appreciated as soon as possible
