The bug is as old as the message coalescing feature in the openib
btl.
Nathan,
Has this bug always been present in OpenIB or is this a recent addition? If
this is regression, I would also be inclined to say that this is a blocker
for 1.8.4. This is a SIGNIFICANT bug. Both Howard and I were quite
surprised that all the while this code has been in use at LANL
in produc
Thanks, Nathan. After a bit more investigation yesterday, this was our
conclusion too; that it is a longstanding bug in OpenIB BTL we just
happened to start triggering the broken flow with some recent changes made
to the default max_lmc parameter. Let us know if you need anything from our
end.

I see the problem. The openib btl does not properly handle the following
call sequence (this is an openib btl bug IMHO):
btl_sendi (..., &descriptor);
btl_free (..., descriptor);
The bug is in the message coalescing code and it looks like extra logic
needs to be added to the openib btl's btl_fre
Can you please let me know when you fix this? I intend to release 1.8.4 by the
end of the week. Since Mellanox is the only member with IB, you folks have been

Hi,
On 1.8.4rc1 we observe the following assert in the osu_mbw_mr test when
using the openib BTL.
When compiled in production mode (i.e. no --enable-debug) the test simply
hangs.
When using either the tcp BTL or the cm PML, the benchmark completes
without error.
The command line to reproduce th
