Sometimes, the ucmatose is being executed, when we execute it on 10.4.3.142:
the first test case that uses the rdma_cm fails, here is a dump from out logs:



Daemon command line: /usr/local/bin/ucmatose
Client command line: /usr/local/bin/ucmatose 11.4.3.142
=======================+ Daemon Output +====================
CMA: unable to open /dev/infiniband/rdma_cm
failed to create event channel

=======================+ Client Output +====================
cmatose: starting client
cmatose: connecting
cmatose: event: 8, error: 8
receiving data transfers
sending replies
data transfers complete
test complete
return status 0




The strange thing is that the next test that tries to use the rdma_cm passes ...
