Duplicate runs when using agendas?
« on: December 13, 2007, 11:14:29 PM »
Does anyone else have a problem with duplicates getting run when using a custom back end with agendas?  We're having a problem with the same agenda work item being picked up at the exact same moment by multiple cores -- sometimes 6 at a time.

Thanks,
  Chris

Hey Trimbo,

     What version of the supervisor are you running?  It will help us to identify the code base for us to look at.
 
     To check the supervisor's version, just open a command prompt and use the
qbping command.  It will return the version of the supervisor and the build date.

     Thanks,
         A

For those who may run into this, the issue was that only the first 16 (IIRC) bytes of an agenda item was hashed.  Since our agenda items were full paths, there was a lot of repetition in that first 16 bytes and a job would be run repeatedly. 

The workaround was to add a counter to the front of the file paths, and I believe in the future PFX will be making it so the first 256 bytes are included in the hash.
