Yippee :-)

It sounds like there is still a calculation slightly off.

I don't see a constant off by 8 remainder issue. In my configuration
most seem fine and the only one which is not off by 20 (SA class header
size) is the following:

Sep 20 05:17:36 292850 [40FFF960] -> osm_vendor_get: Acquired UMAD 0x53cd40, size = 856.

Is this what you are referring to ?

I do also see:
Sep 20 05:16:40 995667 [AB001140] -> osmt_get_service_by_name: ERR 0370: ib_query failed (IB_REMOTE_ERROR).
Sep 20 05:16:40 995673 [AB001140] -> osmt_get_service_by_name: Remote error = IB_SA_MAD_STATUS_NO_RECORDS.
Sep 20 05:16:40 995678 [AB001140] -> osmt_get_service_by_name: Expected num of records is : 1, Found number of records : 0

and some timeouts:
Sep 20 05:17:40 644730 [40FFF960] -> umad_receiver: ERR 5409: send completed with error (method=1 attr=12) -- dropping.
Sep 20 05:17:40 644740 [40FFF960] -> umad_receiver: ERR 5410: class 0x3 LID 0x0
Sep 20 05:17:40 644750 [40FFF960] -> __osmv_sa_mad_err_cb: [
Sep 20 05:17:40 644760 [40FFF960] -> osmtest_query_res_cb: [
Sep 20 05:17:40 644769 [40FFF960] -> osmtest_query_res_cb: ERR 0003: Error on query (IB_TIMEOUT).
Sep 20 05:17:40 644787 [40FFF960] -> osmtest_query_res_cb: ]
Sep 20 05:17:40 644801 [40FFF960] -> __osmv_sa_mad_err_cb: ]
which then resulted in:
Sep 20 05:17:40 644955 [AB001140] -> osmtest_wrong_sm_key_ignored: ERR 0011: Did not get a timeout but got (IB_SUCCESS).
