> Good day everyone,

> After AllisonHouse installed 6.13.10 on our production servers, we noted that 
> on one of our machines, if you fed data from an internal server and, as a 
> backup, an external server…it could cause pqact processes to stop writing to 
> disk if the internal server's upstream LDM was restarted. Weird, huh?

> AllisonHouse, College of Dupage (thank you, Mike Zuranski) and Iowa State 
> (thank you, Daryl Herzmann, aka Superman) hammered the beta versions, and 
> squashed all of the bugs we found. Not to mention, a few people found other 
> bugs on their own, and these got fixed as well with the new 6.13.11 release.

> In the process, we found that version LDM 6.13.6, which we failed back to, 
> randomly crashes under Centos 7, and 6.13.10, the previous version, was 
> stable except for the logging bug that was fixed. However, if you have a 
> satellite dish with a NOAAport ingester, test immediately and upgrade ASAP. 
> And I would strongly recommend everyone else do the same as well, even if you 
> are not having any apparent issues.
> Some of those bugs are serious, even if you don't see them occurring on your 
> servers. Those memory leaks we and Coverity Scan found are not fun…

> Onward and upward!
