Large number of parallel Batch files failing FDMEE to HFM. Can I limit?

Hello, my batch load with FDMEE 11.1.2.4 to HFM is failing when we have a large amount of files (required by client).  It appears that I can only load 8 files at a time in order to run all the way through (export and check) into HFM  11.1.2.4.  Anything more, I get the following error below.  And the error occurs at the "Validate" stage in the process monitor. We've tried to increase the number of connections to HFM but its not helping.

Our batch folder can be filled with about 40 files at a time, in the production FDM 11.1.2.2 (classic) version, this is fine because we can limit the number of files loaded.  Is there a way to do this in FDMEE?  Do I need to, or can I parallel batch a large amount of files?
