Ivan Fedotov edited comment on IGNITE-8619 at 6/20/18 4:38 PM: --------------------------------------------------------------- [~dpavlov], [~ein], Hi! I investigated this issue and found that locally tests failed only when ssh disconnected per timeout. I assume that ssh timeout on TeamCity could be set incorrectly: as one of StartStopNodes tests is started, ssh could be disconnected per timeout. Change ssh timeout on server side is easy, we should add some lines in ~/.ssh/sshd_config file: ClientAliveInternal n - the server send the clients «null packet» every n seconds to keep connection alive, ClientAliveCountMax m - «null packet» will be send m times. I suppose that it can fix flucky tests on ssh connection. What do you think? was (Author: ivanan.fed): [~dpavlov], [~ein], Hi!
