Hi Hal, Viswa,
Sorry I'm joining late on this thread due to the weekend (which starts
here on Friday ending Saturday night).
Is there any conclusion on this one?
No.
The only log I have seen was from osmtest failing to send a MAD.
True.
Looks like a umad issue?
Not sure why you say that. There are other possibilities I'm aware of
here:
Note that that failed sent MAD is one which has a response expected so
this means that the response was not received. It also goes through the
transmit retry strategy (I could see this on the SA side). So the only
thing I can say at this point is that for some reason, the response does
not make it back from the SA to the SA client (osmtest). That's where
this one is right now.
Thanks for the update.

Currently opensm traps SIGINT. There was some discussion to remove
it.
I have currently running some tests on opensm
by killing (SIGKILL) and restarting opensm. So far I ahve not found
any resource leak issues. Is ther a plan to remove that
signal handler. Ideally it should not exist.
Eitan stated that this was historical in nature for gen1 drivers
which
had resource tracking problems: "if OpenSM left without cleaning up
all
used resources (like MAD buffers and UD-AVs), the driver oops'ed."
I think that (eliminating the handler for SIGINT) can at least be
done
for OSM_VENDOR_INTF_OPENIB and leave it there for the other vendor
layers for starters. I will experiment with gen2 and let you know.
Does the patch below do what you want ? Can you try it ?
