I have been noticing scheduler.aspx errors in event log. Well we figured it out. When we had the site open on our Development machines, the error would occur on the production site. Apparently the local copy of the site which was an exact copy of the DB and Kentico from the production site was trying to run the scheduler remotely on the production site. Once we shut off our dev sites the problem went away.

Just an FYI for others who encounter the same issue.
