You are alternating between two values:
1217485404
1217489802

It looks like the first two calls to gettimeofday() worked and then it started failing. I can't say why, but I certainly don't understand why you are blaming a multi-core environment. System calls return -1 and set errno when they fail. Checking that is the documented way to discover the reason for the failure.
