Patrick requested that people would respond to the e-mail he sent
around last week. 

Ben mentioned that Shourov appears to have found a data corruption
issue.  Some data being repeated ~1/16 sec of repeated data from time
to time.  Only found it so far in FB1 data.  As many as a hundred
channels might be affected.  Many of these channels were only added
recently at LLO.  Greg mentioned that if we switch everything to FB0,
it will fall over.  CDS will have to work on this.  

Rolf is the head guy.  Alex will be the person at the LSC meeting.
Has gone up the food chain already.  Vern knows about it.  Dave
Barker.  Ben and Keith are looking into it.  On that side of things,
they don't look at frames.  Shourov is looking into it.  

Ben is saving frames from both framebuilders.  This came up from the
output of the S5 search;  Duncan noticed this thing that he passed it
on to Shourov.  It is exactly on the 1/16 second boundary,  so it is
easy to diagnose.  Shourov is working on the problem.  

Ben has been checking what is happening at LLO.  Looking at the CRC
checksums,  LLO does not show this problem since last Friday.   

Ben's scripts have identified the times.  Shourov is checking which
frame-builder has the problem.  This information will get to Keith
Riles and to Vern Sandberg.

There were no urgent reports from the project Librarians.  

Duncan reported on the SegFind server/client that he developed and
that Igor is going to take over the maintenance of.  His presentation
is at

Warren asked about the licensing.  It is available under the IBM
scholars program.  It is linked from the segfind documentation site.
Duncan thinks this license is available in all of the countries we're
interested in for academic use. 

Duncan also linke something else in the web site with information
about the QReplication.
