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? The only log I have seen was from osmtest
failing to send a MAD.
Looks like a umad issue?

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 ?
