Looks ilke you need to run with '+isomalloc_sync', but there might be other issues too

  • Subject changed from megampi test hangs for pami-linux-ppc64le-smp build to megampi test hangs for pami-linux-ppc64le-smp & pamilrts-linux-ppc64le-smp builds

Seeing the hang even with '+isomalloc_sync'.

Similar hang is seen for pamilrts-linux-ppc64le-smp build as well. (https://charm.cs.illinois.edu/gerrit/#/c/3141/)
