I guess this failure happened in osm_db_init() function (see in OpenSM
log). This returns '1' on failure which is translated to
IB_INSUFFICIENT_RESOURCES error code.

Now in OpenSM most functions return status as 'ib_status_t' although not
each such function (just as osm_db_init()) is IB related and not every
error is IB related. I agree that this practice is not very successful
in general.
