Hi,
Just following up on this. I had a closer look at this part
which is common to most of the deadlocks
#6 0x0fd176d8 in opal_mem_free_ptmalloc2_munmap
(start=0xf2af, length=65536, from_alloc=1)
at opal_ptmalloc2_munmap.c:74
#7 0x0fd18268 in new_heap (size=196608, top_pad=131072) at
Ewww yikes. This could definitely be an issue if we weren't
(multi-thread) careful when writing these portions of the code. :-(
