* ENT-2569: Integration test to simulate Rpc/FlowWorker restart. Initial analysis shows that 15-25 MB cannot be accounted for after RpcWorker restart. Please see below for stats sample. I will need to run memory profiler to understand where the memory is going. Sample 1: ``` Memory stats @Very beginning - Used memory: 66,167 KB, Total memory: 1,158,144 KB, Max memory: 7,414,784 KB Memory stats @Between restarts - Used memory: 214,952 KB, Total memory: 3,228,160 KB, Max memory: 7,414,784 KB Memory stats @Very end - Used memory: 231,285 KB, Total memory: 3,226,112 KB, Max memory: 7,414,784 KB ``` Sample 2: ``` Memory stats @Very beginning - Used memory: 65,649 KB, Total memory: 1,125,376 KB, Max memory: 7,414,784 KB Memory stats @Between restarts - Used memory: 202,542 KB, Total memory: 3,390,976 KB, Max memory: 7,414,784 KB Memory stats @Very end - Used memory: 217,969 KB, Total memory: 3,387,392 KB, Max memory: 7,414,784 KB ``` * ENT-2569: Repair FlowWorkerTest and make it use signed network parameters. * ENT-2569: Take flow worker up and down multiple times. * ENT-2569: Add memory consumption stats. Sample output for 10 iterations (1 warm-up and 9 subsequent): ``` Memory stats @Very beginning - Used memory: 126,495 KB, Total memory: 1,599,488 KB, Max memory: 7,416,832 KB Memory stats @After warm-up round - Used memory: 172,411 KB, Total memory: 2,096,128 KB, Max memory: 7,416,832 KB Memory stats @Testing done - Used memory: 196,912 KB, Total memory: 2,213,376 KB, Max memory: 7,416,832 KB ``` So during 9 iterations/restart cycles we have lost ~25MB. * ENT-2569: Re-structure the test in preparation for 2nd legal name. * ENT-2569: Mote test re-structure. * ENT-2569: Introduce BankB into the test scenario.
