Dummytask timeout stuck

System

I have a dummytask to wait for 1 minute in one of my workflows. Occasionally the job will wait about a minute, then proceed. But on other occasions, the dummytask will get stuck for much longer than a minute, sometimes several minutes before it continues on. WTF? Seems like such a simple concept. Has this happened to anyone else?
