 ### Docker containers exhausts space due to the `json-file`
 
 Docker's [default logging driver is `json-file`](https://docs.docker.com/config/containers/logging/configure/#configure-the-default-logging-driver), which performs no log rotation by default. As a result of this lack of rotation, log files stored by the `json-file` driver can consume a significant amount of disk space for containers that generate a lot of output. This can lead to disk space exhaustion. To address this, use [`journald`](https://docs.docker.com/config/containers/logging/journald/) as the logging driver when available, or [another supported driver](https://docs.docker.com/config/containers/logging/configure/#supported-logging-drivers) with native rotation support.

+### Buffer overflow error when starting Docker
+
+If you receive this buffer overflow error, you should purge old log files in
+`/var/log/gitlab`:
+
+```plaintext
+buffer overflow detected : terminated
+xargs: tail: terminated by signal 6
+```
+
+Removing old log files helps fix the error, and ensures a clean startup of the instance.
