[MarkLogic Dev General] Directory delete

[vjprasanth@gmail.com]

Hi Mike,

  I will check that. I am using eval to make sure  most of the exceptions are caught and handled properly, which is not given in the code.  

Thanks,
Prasanth

I wonder if the flex-rep scheduled task is competing with the deletes? Try setting file-log-level to "Debug", and look in ErrorLog.txt for any XDMP-DEADLOCK warnings.

Why is this code using eval? Why not simply delete the document in the main query?
