Hello,
Can someone from Mellanox tell me what the vendor error 0x32 means? I am getting this error for wc.opcode 128 (IB_WC_RECV) wc.status 4 (IB_WC_LOC_PROT_ERR). I am running ofed 1.5.2 and am getting it on both rhel5 and sles11
Thanks in advance!
Usha

You can't count on the wc.opcode when the status isn't success (0), and
yes, we're also saw tons on "ib0: failed recv event status=4, wrid=154
vend_err 32)" errors when running iscsi/tcp over IPoIB stress from
windows client to linux node acting as the iscsi target and using ofed
1.5.2, it starts to look like DoS attack is possible here.
Or.

This error means corrupted MPT or PD violation
