It isn't clear what this test is trying to do? The client is deliberately evicted and then the HSM command fails because the client is evicted... So this could be some race condition, or maybe a patch related to client eviction or HSM was landed recently? This subtest has only failed twice in 500+ runs, both on b2_15, both on full-part-2, about 30 sessions that ran that way.
