Found SMB related issue I am getting this error.
But turns out, if we "restart" smb service in FreeNAS it goes away.
As you can see. This is a part of my Youtube video capture while shooting episode I got this bug. In fact I found this happening randomly few times past several months. I felt today to bring it to your attention.
NOTE: this goes away sometimes after FreeNAS reboot. Or sometimes via just "smb" service restart (disable/enable) in FreeNAS.
I tried it in the SMB settings. SMB1 enable/disable, etc.
But doesnt seem to address. I just randomly disabled n enabled SMB service in FreeNAS.
It addressed the problem :)
