strange CMIS errors

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I'm seeing these stack traces sporadically.  It does not seem to be on the same object every time, so I can't really figure out what's wrong.  Could it be a network glitch?  If so, how do we improve this (retries or something?)?

Any ideas what this is, and how I might be able to troubleshoot it and/or avoid it?
Thanks,

How large are the objects you are trying to persist? Is there any consistency between the file size and the occurrence of this error?
