[mpich-discuss] assertion failed in socksm.c it_plfc->revents when trying mpptest

[Pavan Balaji]

The problem with the test suite seems quite weird to me. We run the 
MPICH2 test suite several times in the nightly scripts as well as for 
our local testing every day, and we never saw any such problem.

Does the "cpi" test in your build/examples directory work fine?

  $ mpiexec -n 4 ./examples/cpi
