OK, you didn't mention that it is the same PID every time. In that case my first suspicion would be a bug in pgrep. If it happens again, I suggest you use pgrep -lf. Maybe the output gives a hint. (Also note that ps cuts after 80 columns. Sometimes the information you're looking for is after column 80, so I recommend to always use -ww, especially when the output is used for matching in scripts.)
