Warning C271A avoid

Hello everybody!

I just got the warning C271A. It happened for the first time in weeks, and I have been using the same program. I have about 30 threads with one sync() each.

It did not happen again, but I am afraid that it could occur one more time.

Anyone could give a tip? Information on the service manual and about sync() is very brief.

Thanks in advance,

Kind regards!!
