dockerd left open file descriptors do deleted /var/log/journal//.journal files
I'm using dockerd with --log-driver=journald.
After few days it left many open fd to files in /var/log/journal:
ls -l /proc/$(cat /var/run/docker.pid)/fd |grep deleted |wc -l
6250
which store place on disk.
Steps to reproduce the issue:
- install docker, configure it to use journald
Describe the results you received:
ls -l /proc/$(cat /var/run/docker.pid)/fd |grep deleted |wc -l
6250
