We got a machine crash on a machine with the following attributes:

I attached the test to this email.


This test does the following scenario:
    restart the driver
    start a user level application that allocate N multicast groups (it 
is being executed in the background)
    sleep for a while (to let the later application get the mcgs)
    start the SM (in the background)
    sleep for a while
    kill the SM
    wait until the user level application will ends

We do it in a loop for the following values of N: max_mcast -1, 
max_mcast -2, max_mcast -3

I executed the following command (only one side is needed):
# ./ib_mcast_full.bs --server

The test need to be executed when the driver was loaded and the opensm 
isn't executed in the background.
The user level application uses the VL library which can be found in:
    https://openib.org/svn/trunk/contrib/mellanox/ibtp/common/tools/vl

I hope that this will help you ....
