Hi Anatoly,
Missed Hal's response when I wrote mine.
As Hal says, Windows SM version is old. IMHO, fixing problems like
you've reported it is not even an option, because it will involve
serious changes to existing features or implementing additional ones,
which was already done in the Linux OpenSM.
So I can only reiterate what Hal has already said - OpenSM in Windows
needs to be updated to the latest and greatest.

Hi Anatoly,
I need more details:

Hi,
Our client reported problems running over 192 concurrent jobs with
OpenSM.
What kind of cluster does your client have?
How many hosts? How many switches?
What do these jobs do?
Are these MPI jobs? Do they use/create multicast groups? Something else?
How many processes each job has?
The jobs are executed several times. After a while the memory usage of
OpenSM goes to ~30MB, cpu usage to 100% and eventually the node
freezes and needs to be reset.
Is the problem reproducible?
Can you send me SM log?
-- Yevgeny
Configuration:
Winof rev 1596 (~rc1)
ConnectX HCA
Windows 2008 x64 with HPC pack rc2
NetworkDirect is installed
OpenSM is running as a service on the head node.
About a hundred nodes are used (maybe more, I don’t have exact number
yet)
Has anyone any thoughts about this?
Thanks,
Anatoly.
