What is the OS of the deployment server?
kill -USR1 $(cat /var/run/confluent/pid)
This should produce a /var/log/confluennt/hangtraces
Would be interesting to see if there's ansible related stacks in hangtraces
that seem stuck...

Doing a "kill -9 27588" (on apiclient) causes the installation to 'finish'.
After the reboot, and after "firshboot.sh" does its thing, we have the
following from 'ps axf':

This causes the "/var/log/httpd/ssl_access_log" to start filling up. A
subsequent reboot, where "firstboot.sh" is not run, has the the system coming
up without "apiclient" running, and so there's no longer 'spam' in
"ssl_access_log".
Running "apiclient" manually from the CLI with the exact options causes a bunch
of stuff in "ssl_access_log":
"""

at the same time as the above is being generated, there is nothing in
"/var/log/confluent/trace" or "stderr”.
