[users at bb.net] Slave not logging

[Barta, Hank]

OS Ubuntu 14.04 LTS (inside a Docker container, host OS is the same.)
Buildbot version: 0.8.8
Twisted version: 13.2.0
Docker version 1.9.1, build a34a1d5

The slave starts and runs but there is nothing in the log. Other than that it seems to operate normally.

File perms on the directory used by the slave are:

root at 6cdfea974f8e:/# ls -lR /var/lib/devops/buildbot/slave01/
/var/lib/devops/buildbot/slave01/:
total 12
-rw------- 1 bbslave bbslave 1304 Aug  5 14:36 buildbot.tac
drwxr-xr-x 2 bbslave bbslave 4096 Jul 29 19:09 info
-rw-rw-r-- 1 bbslave bbslave    0 Jul 29 19:10 twistd.log
-rw------- 1 bbslave bbslave    2 Aug  5 14:36 twistd.pid

/var/lib/devops/buildbot/slave01/info:
total 8
-rw-r--r-- 1 bbslave bbslave 34 Aug  5 14:36 admin
-rw-r--r-- 1 bbslave bbslave 71 Aug  5 14:36 host
root at 6cdfea974f8e:/#

The slave (?) creates the PID file and otherwise seems to operate normally.
(Master uses analogous commands and does operate normally. Except for mail notification, but that's a different subject.)
Slave and master are executing in the same container.

Relevant commands to create the slave, copy the files to an alternate location and start the slave are shown:

First run when the Docker image is built:
  ENV SLAVE_HOME   /home/bbslave/slave01# set variable
  RUN buildslave create-slave ${SLAVE_HOME} localhost:9989 slave01 pass# build slave, files in slave user dir

In the startup script
  chown -R bbslave.bbslave /var/lib/devops/buildbot/slave01 /home/bbslave# make sure all relevant files are owned by slave user
  su -c "cp -R /home/bbslave/slave01/* /var/lib/devops/buildbot/slave01" bbslave # copy files to directory shared with host
  su bbslave -c "/usr/bin/buildslave start /var/lib/devops/buildbot/slave01"# start the slave

When I first began building this the slave was logging normally but stopped at some point for reasons not obvious to me.

Thanks,
hank
