[Condor-users] Java job and missing output.

[Michael Remijan <remijan@xxxxxxxxxxxxx>]

Hello,

I wanted to report what I think is a bug.  I have a Java job that loops 
over a 10,000 line input file and executes a database query for each 
line.  The results are then written to a results file.  There is always 
only 1 line written to the output file.  This means with a 10,000 line 
input file the output file will also be 10,000 lines.  While doing some 
performance testing we found this is not always the case.  A few of the 
jobs produced output files of 9,999 lines and even 9,995 lines.  Further 
analysis showed a similar gap in the Standard Out file.  The behavior is 
almost as if the output was buffered to be written, never written, and then 
lost.  I have also confirmed this is not a problem with the Java job.  No 
exceptions were thrown, no errors encountered.  It's just that a few lines 
that were suppose to be written to standard out and to an output file vanished.
