Hello,
I have a problem with rsync and would like to describe how it behaves:
I have connected my Synology NAS to Unraid via "Unassigned Disks" using SMB and occasionally back up my data there.
After approximately 1.5 to 2 hours, Unraid completely freezes. I can no longer access any of my Docker containers, shares, or the web GUI. However, Grafana still manages to capture some data. The red line in Grafana shows that from the moment the CPU reaches 100% usage, there are continuous interruptions.
It doesn't matter which rsync tool I use—I experience the same issue with LuckyBackup and the official rsync Docker container. The behavior is always the same. In the end, I have to physically unplug the server to restart it. If I don't run rsync, my Unraid system can run for more than 20 days without any problems.
I've only noticed this issue since Unraid 7.0.0 Beta, but it might have already started with the last 6.x version—I'm not entirely sure since I don't run rsync frequently.
In the attached log file, I started rsync twice and eventually experienced the freeze:
-
The first time around 10:19:50 (Line 221):
- php-fpm[11959]: [WARNING] [pool www] child 2047801 exited on signal 9 (SIGKILL) after 187.327662 seconds from start
- After this, more similar errors appear.
- The second time at 13:38:38 (Line 692).
I've done some research and found multiple reports from other users experiencing the same rsync-related freeze.
It would be great if someone could help me resolve this issue.
