@trey-ornl , @GeorgiadouAntigoni , @hagertnl - I'd like to talk about this at our next GPU MPI meeting (I'll forward the invite to @ashesh2512 ).

The hope is that in the next MPI + ROCM release all the edge case memory leaks will be resolved and we can just strop back to the "here's how to enable the IPC signal cache and tune the IPC cache size" documentation.
