nfsd Not tainted

[mooky]

I've been getting some times when my shares just drop over the last while (6.9.2 and 6.10.3 after a recent update 4 days ago), so I started investigating. I found a legit RAM problem (using memtest), that I believe I fixed by modifying BIOS XMP profile settings.  After fixing the RAM (ran 3 passes of memtest successfully where previously it failed on first pass), I took the array offline, and ran XFS filesystem checks which didn't reveal anything interesting, put the array back online, and I thought .. ok, everything is okay now.

 

After 16 hours back in production, I just looked at my log and I got the below cut/paste again (I had an identical nfsd not tainted error previous that I didn't save at the time).    Now I'm not sure if this is related to shares dropping, I wasn't around actively using my network when this error happened, but thought I'd see.  I have NFS turned on in unRAID, and the "Tunable (fuse_remember)" set to 3600, I have more enough RAM, so that's not an issue, I previously had it set even lower to 600.  (sitting at roughly 3 of 16 GB RAM used).

 

Let me know if you require anything else for troubleshooting.  Maybe this is completely normal occasional network crapping behavior ("not tainted" leads me to believe ... maybe?), and my share problem crapping out is solved since this time despite the error my shares are still there, I just don't know. I don't have enough time with the array back operational yet to have any definitive answer, but thanks in advance.
