Hi Everyone,

There is one type of real recon error that is common, the rest appear to be random 
failures that are fixing themselves by rerunning.  Maybe it happens when there were
no tracks reconstructed in a given file, based on this error message and the fact
that it frequently happens when there was only one file in the run (and shouldn't have
been processed anyway).  But the symptoms are not isolated to only single-file runs
nor the last file in a run.

This one below came from run 5754, file #4 (not the last file in the run, and a run that
should be reconstructed well for ecal calibration purposes).

Here's the list of files of relevant log files:
