you shouldn't increase/decrease anything. You should look in the
output file if there are other error messages. Then you should
verify whether this error is reproducible ([referrably by running
it on a different machine). If it is, please provide code version,
input data, execution detail so that the error can be reproduced.
If it is not: your compiler or MPI libraries are, with very high
probability, buggy
