Writes fall to zero bytes after a few seconds

Every time I try to copy a file to the NAS, it starts out fine and then the writes fall to 0 bytes and then eventually errors out... on the latest firmware. A reboot seems to fix the issue for a while but it comes back after a few weeks of uptime..... what gives? Load average is low...

    Is this 4.2.31?  Or something else?

     

    Do you have any add-ons installed on the NAS?  Do you use ReadyDLNA?

      Yes running a Plex Server & Unifi controller and that's about it... and just the normal services that come with the readynas. Running OS 6.10.1... running a defrag right now which will take a long time - the odd thing is it doesn't show any logs that the defrag is running... weird.. 

       

      The write performance issues happened even before I put plex on it.

        When you say a reboot resolves the issue temporarily, is that a reboot of NAS or computer?

         

        Any chance you could pcap a failed file transfer? Ideally capturing the whole session setup, so close all windows explorer windows and delete all existing entries in 'net use', then start pcap -> open smb share -> start transfer -> once speed hits 0, wait 10 seconds (or until it errors out) and stop pcap. This should help narrowing down the issue.

         

        If you want you can send the pcap to me in private as well.

         

         

  • Yes the resource has been mongodb. It is the most $#% and resources consuming database possible. Altough in some cases, programs or apps dont support any other db than mongo. It stalls system resources in some moments but pretty / ugly often. Havent invented with my research what it does. Planning to install it on SSD, instead of harddrive as usual. Could change it. Hopefully. It is also one of the most drive space consuming db. 🙂
