In general this is unavoidable. There will always be problems on which the heuristics get lucky and others on which they don't. Using an "easier" logic declaration does not necessarily always mean that the solver will be quicker. Illustrated on this particular example problem, Z3 times out with the logic set to QF_LIA using smt.random_seed=0 (that's the default) and smt.random_seed=1. Keeping the logic set to QF_LIA, but using random seeds 2-9 all terminate quickly, where 7 is a little bit slower than the others.
