---------------------------------------------------------------
[~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?

> Now there is a problem with launch remote node via ssh. Initially was an
> assumption that it's due to remote process has not enough time to write
> information into log:
> [IGNITE-8085|https://issues.apache.org/jira/browse/IGNITE-8085]. But this
> correction didn't fix [TeamCity
> |https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=6814497542781613621&tab=testDetails].
>
> So it's necessary to make launch remote node via ssh always succesful.
