[mpich-discuss] Regarding issue with MPICH 3.2

[Zhou, Hui]

Thanks, Neeraj singh.

To confirm, you always have this error with the profiler, but intermittent without profiler? When the error shows up, does the error show up at the beginning of the application, middle of the application, or near the end of the application?

Hi Neeraj singh,

To clarify, does this error only happen when you try to use the profiler tool?

I am using the MAQAO profiler tool to collect data based on sampling. While launching an application for multinode some issues I'm facing.
Kindly check the attached problem lines and clarify the same.
Thanks & Regards
