> We've seen a number of failing transaction system tests. After investigating a few of these, I found that this came down to transaction timeouts which were due to partition unavailability. The test rolls the brokers in the cluster, but it does not verify that URPs have cleared after restarting each broker. This means that it is possible for partitions to go under min isr or even offline. In the case of a hard bounce, the time to recover may be quite long because of the default session timeout of 18s. It would be good wait for URPs to clear instead.
