Good Morrow fellow UnRaidians. If I may distrupted your daily routine to humbly ask for you for assistance. 

 

For the last few weeks I have had to reboot (sometime multiple times) daily. 

I see this spamed in logs: 

 

Mar 10 12:05:45 nas  shfs: fuse warning: munmap(0x14df0ee02000) failed

Mar 10 12:05:45 nas  shfs: fuse warning: munmap(0x14dfa32e3000) failed

Mar 10 12:05:45 nas  shfs: fuse warning: munmap(0x14df4642a000) failed

Mar 10 12:05:45 nas  shfs: fuse warning: munmap(0x14df46448000) failed

Mar 10 12:05:45 nas  shfs: fuse warning: munmap(0x14df5de08000) failed

Mar 10 12:05:45 nas  shfs: fuse warning: munmap(0x14df4640c000) failed

 

Symptoms:

 

My shares slowly stop responding/loading. Docker services stop responding. WebUI remains responsive for a while but it too goes unresponsive. SSH over (takes forever), get in and run powerdown -r. Sometime it will kick off and reboot, most of the time it just stares back at me in defiance. So I have to issue powerdown -r again, then it will follow directions like it didn't understand the first time....

 

One intresting side note, after reboot I have to stop Docker, and then start again in order to get SWAG to talk with anything. 

 

Attached both diagnostic and syslog file post the reboot of the most recent event. 

 

I have googled (normally my google-foo is stong), but only found refrences to FUSE statement being related to NFS shares. The solution that work for that person was to rollover to Samba shares. This is shomething I would very much like to not do. 

 

So, I beg upon you the UnRaid Lords of endless knowledge... what am I missing? Doing wrong? Ignoring?

That would likely be your best best.

Hello,

i have the exact same problem since some time.

Additionally my server is slowed down (e.g. network performance) when this errors occur in the log:

Apr  1 05:17:12 UnRAID  shfs: fuse warning: munmap(0x14a135df8000) failed

 

What can i do to fix this issue?

And NO, use only SMB shares is not an option on a linux system with several other systems in the network which must use the NFS share...
