Hi guys,

I'm suffering from this problem for a few weeks, having no idea what to do now...

First, this is my Nas info:

• System: OMV5
• CPU: AMD Ryzen 3 5300GE
• Motherboard: Asus b450m PRO GAMING (2.5G)
• Drive: 4 x 2TB SSD
• Memory: 64GB

The thing is, I use 1G router in my home network, NAS is connected to it using cable, this works great, I can view any movie up to 80m/s on my phone using SMB or SFTP.

Weeks ago I run a script to update all docker containers on NAS, including qbittorent, jellyfin, sonarr and etc., and update system packages. Days later I found it stucks when I open a Blu-ray movie on my phone. So I checked network status (MXPlayer on phone) and it shows only 500kb/s. The problem solved by reboot NAS, but if I drag progress bar too quick or many times, it reproduces again, can't recover until reboot... I also found after downloading movies using qbittorrent for hours, it happens.

So I tried:

1. Looking into the system log and other logs under /var/log/, but nothing related is reported in logs.
2. Using different file sharing protocol, smb, ftp, sftp, ftps, when the problem happens, they all transfer at around 500kb/s.
3. Looking into result of ethtool, it shows the network is at 1000M/s level.
4. Use iperf3, the network from NAS can go up to 958MB/s both tx and rx, but 7MB/s when the problem reproduces.
5. Copy a large file on drive A to and from drive B, average speed is 200Mb/s.
6. Using netstat to see packet loss, but it shows 0% loss.

I'm currently using a stupid solution: script to reboot at mid night... But it interrupts a lot of task of my services.

So, is there any tool or way I can try to solve it? Thanks!!!!
