LDM 6.5.1 released

[Steve Emmerson]

Dear LDM user,

LDM version 6.5.1 is now available from the LDM homepage at

     http://www.unidata.ucar.edu/software/ldm

or from

     ftp://ftp.unidata.ucar.edu/pub/ldm/ldm-6.5.1.tar.Z

This release fixes a couple of bugs and performance issues with the 
previous release (version 6.5.0).  Specifically, the CHANGE_LOG entry 
for this release is (in it's entirety)

     Improved LDM performance:
         Of downstream process during startup by changing
         product-queue access-mode from writing to readonly
         when searching backwards for matching product to
         avoid file write-locking contention.

         Of upstream process during termination by
             Adding potential termination point to each data-product
             during initial backward search of the product-queue.

             Closing downstream connection upon receipt of SIGTERM.

         Of downstream process during termination by closing
         downstream connection upon receipt of SIGTERM.

     Modified the "pqact" utility:
         Corrected behavior of the "-overwrite" option of the FILE
         and STDIOFILE actions.

         Ensured proper behavior of the "-log" option of the FILE
         and STDIOFILE actions regardless of operating-system.

Basically, the "-overwrite" and "-log" options now work correctly and 
the entire LDM system should now start and stop more quickly.

My thanks to Gilbert Sebenste, Daryl Herzmann, and Rob Dale.

Those of you who refrained from installing version 6.5.0 because it was 
a "dot-zero" release may now pat yourselves on the back.  ;-)

Steve Emmerson
