I've been having some issue with Unraid having high CPU usage. I do not run any VMs, and only the Krusader docker image. The hardware is a Xeon L5520 single CPU with 6Gb of ECC unbuffered RAM. The Unraid server (version 6.6.6) has 9 drives in the array (2 parity), 1 x 240gb ssd cache, and 1 x 1TB 7200RM harddrive as an unassigned device. I run all my VMs in a separate ESXi server connected directly with 10Gb ethernet connection directly. Deluge runs in a VM in this ESXi server and connects using NFS. Deluge is configured to use a folder on and unassigned drive so that downloading does not require real time parity calculation. I do really prefer using separate NAS and applications servers to separate function within my network. The ESXi server also runs my Plex server. My CPU seems to often have high usage, and deluge often errors on large downloaded files. I've linked a video which shows average cpu usage that I've seen over the last few months. I'd be willing to purchase an upgraded cpu if i though it would help (ie xeon x5680), but I'd like to make sure it would actually help my use case.

Awesome! This has been driving me crazy on and off for a year.

Changed by NFS mount options on the client FSTAB from: nfs rsize=8192,wsize=8192,timeo=14,intr to: nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0 seems to have resolved the issue. The memory & CPU usage went way down and have been stable for about 14 hours. Thanks for the help yesterday.

Ok thanks for the help today, getting closer.

Ok, uploaded. tower-diagnostics-20180114-1431.zip

THanks for the info, but I spoke too soon lol. Lost user shares again. I have 8gb of memory, no vms and only Krusader docker running. I didn't see these errors in the log on the previous crash.

Seems to be working so farf. And the plugin issue update is resolved now too (some weird router error). Thanks for your help. Is there now a known issue with the preclear plugin and v6.4?

Just lost user shares again. Here's what's in the syslog. All drives are approximately half full.

sorry my bad, multiple windows open.

Thank you. I'll add that rule and test it out. Butr things have gotten worse instead of better. My shares are randomly disapperring now. 4 times in past 16 hours. They re-appear when I reboot. I think i'm going to roll back to 6.3.

I get request timeout for any host on my network trying to ping google dns, but I'm using 8.8.8.8 as my main dns in pfsense and can browse internet fine. I can ping github.com directly and the domain name resolves fine: Screenshot 2018-01-13 15.53.31

No Check for updates button in the right hand corner on the Plugins page at all. Reloading the page takes a while, but still shows unknown.

I didn't have this problem before upgrade. I can browse github.com from all computers on my network, and I can ping github.com from the Unraid terminal window. No firewall logs related to the unraid server or github.com in pfSense either. Any ideas?

Thanks Squid, that fixed the log issue, but still not able to see status of all Plugins

I've got the certificate provision by adding the custom line to Pfsense DNS resolver. I had to open the terminal window and ping google.com first before I could get the cert to provision. If anyone is having problems getting the Cert to provision, give that a try. I'm having problems with plugins. All statuses show "Unknown" on the plugin page and I am receving this error: Jan 13 12:25:21 Tower root: error: /plugins/unassigned.devices/UnassignedDevices.php: wrong csrf_token Jan 13 12:25:23 Tower root: error: /plugins/unassigned.devices/UnassignedDevices.php: wrong csrf_token Jan 13 12:25:23 Tower root: error: /plugins/preclear.disk/Preclear.php: wrong csrf_token
