Usually, to much hardner will cause a brittle result, to little gives you slow cure or low strength results.
I think this is the most likely answer, the mix was contaminated. I always use appropriate mixing components to mix epoxy in, such as mixing cups and mixing sticks. I also only use BSI Adhesives, I've found over the years that their adhesives are always the freshest and most consistent from batch to batch.
