[ofa-general] Multiple Apps attempting to register as reportprocessors

[Anton Bodner]

We are using the umad interface [umad_register ]... with the capability
bit IB_MAD_METHOD_REPORT set.

The method returns -1 (EPERM), and the kernel logs the error:
Ib_mad:Method 6 already in use.

And yes - I did mean (as you suggest)one subscriber per class, method
and PORT.

application.

What APIs are you using ? What is the specific error message ?

Presuming you are using unsolicited MAD registration, only one
subscriber is allowed per class, method, and port (rather than node).

                                              port

Not as far as I know; maybe others know otherwise.
