I am aware of at least one issue that occasionally fails the tests, specifically the distributed-transactions-test. Command "push action -j eosio issue {"to":"eosio","quantity":"1000000000.0000 EOS"} --permission eosio@active" occasionally kills the non-bios nodes. Since this happens after set_prods, block production stops failing test. The log tail is:
