@ -420,6 +420,32 @@ Once a week or so it's good to run `remove_orphan_files.sh` to save disk space:
5 4 * * 1 rimu cd /home/rimu/pyfedi && /home/rimu/pyfedi/remove_orphan_files.sh 5 4 * * 1 rimu cd /home/rimu/pyfedi && /home/rimu/pyfedi/remove_orphan_files.sh
``` ```
If celery is hanging occasionally (we're looking into it but it's a hard one to solve), put this script in /etc/cron.hourly:
```
#!/bin/bash
# Define the service to restart
SERVICE="celery.service"
# Get the load average for the last 1 minute
LOAD=$(awk '{print $1}' /proc/loadavg)
# Check if the load average is less than 0.1
if (( $(echo "$LOAD < 0.1" | bc -l) )); then
# Restart the service
systemctl restart $SERVICE
# Log the action
echo "$(date): Load average is $LOAD. Restarted $SERVICE." >> /var/log/restart_service.log
else
# Log that no action was taken
echo "$(date): Load average is $LOAD. No action taken." >> /var/log/restart_service.log
fi
```
Adjust the echo "$LOAD < 0.1" to suit your system.
