Truncate table failing (intermittently), no errors presenting.

I have a basic load proc (loading a staging area.) that truncates a target table just before inserting fresh data in said table, all wrapped in a distributed transaction. What happens (only with certain tables and very inconsistently.) is the truncate will fail (no error) and duplicate data ends up in the target table since no wipe actually occurs. This proc only started having this issue when we went from SQL 2008 to SQL 2014. Ideas, notions, thoughts?Thanks in advance!
