[mpich-discuss] Maximum number of communicators

[Jeff Hammond]

It's 2048 in all MPICH2-derived implementations that I know about,
including the ones used on BGP and BGQ.

Since I know what your issue is already, I think the problem has
something to do with context id leaking.  You should post your test
code.
