Subject:        Problem :- Duplicate Tests/Samples for Wagerup Lab in WAO LIMS

On a random, infrequent interval duplicate tests/samples are appearing in WAO LIMS for the Wagerup Lab.

This has been occurring for all Wagerup Lab instrument PCs that send data to LIMS.  Approx 1-2 samples/instrument/day have been duplicated.  This was caused during the copy of results from the instrument PC to the LIMS.

I am guessing but it appears that while the instrument PC is copying the file the LIMS parser starts processing it.  The instrument PC then fails to verify that it has arrived on the LIMS and later resends the queued result file.

I have implemented a change this afternoon that hopefully will resolve this issue.  Now the result file is copied to LIMS with a 'tmp' file extension and then when the copy is completed renames the file to the correct file extension.
