I am occasionally getting the following errors. My searches have not yielded anything helpful yet.
I am using SQL Server 2014 Integration Services with SSISDB Catalog loading data to another SQL server.
The SSIS Package is executed in a loop from the parent package 10.000+ times during a typical load.
The error typically occurs early on, usually with in the 3-6 iteration through the loop. I have not seen it happen the on the first or second iteration.
Rerunning the package once or twice seems to resolve the issue for a while.
Error : -1073676264 : Error loading value "<DTS:ConnectionManagers xmlns:DTS="www.microsoft.com/SqlServer/Dts"><DTS:ConnectionManager DTS:refId="Package.ConnectionManagers[ABC Flat File]" DTS:CreationName="FLATFILE"
DTS:DelayValidation="True" DTS:DTSID="{AC6FBA97-8F7F-410A-9A58-61A7BDF93566}" DTS" from node "DTS:ConnectionManagers".
Error : -1073659899 : The connection type "FLATFILE" specified for connection manager "ABC Flat File" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager
for an unknown connection type. Check the spelling in the connection type name.
The odd thing is it works 99% of the time. When it does fail, it did work in the previous iteration just a few seconds earlier.
At the same level there are 3 other FLATFILE connections defined the same way, they have not encountered this error, but I am assuming that may due to this connection comes first alphabetically.
The ConnectionString property is determined by a expression containing a variable @[User::ABCFlatFile]
Any thoughts on Troubleshooting this issue?
Thanks much,
