SGP/MWR/B5 - Intermittent missing data

Starting on 9/2/07 data have been intermittent due to frequent software crash. Large 
chunks (several days in duration) of data are missing. In March 2008 the fiber optics 
connections were checked and several faulty points were identified. The connections were 
repaired. Since then the instances of software crashes are much reduced.
