[Ncep.list.idp.mrms.users] MRMS LDM Users: Transition to Boulder

Thu Aug 11 17:00:51 UTC 2016

Hello everyone,

Be advised that LDM 6.13.4 is out. This has fixed a number of major bugs that were going on with the LDM; 6.13.4 is certainly more robust than the 6.12 and earlier series. On my CentOS 6 servers, it actually decreased the load average by up to 25%. It is worth the upgrade.

We will monitor for the rest of the day and see if this is consistent. We had done the same yesterday with our local LDM and did not seem to make a difference, but maybe things have stabilized some since then?

Overnight, the grid dissemination has been sporadic, missing 01-05z and sporadic during the day yesterday also, and the grids that have been making it in are coming in late (up to 46 past the hour), whereas it was normally coming in at 04 past the hour. The Hydo applications on A2/Edex run at 24 past the hour and causes artifacts in the QPEs produced overnight when the grids are missing because of latency issues and is causing extra QC work during what is a significant rainfall event.
