May 18, 20206 yr All, This is bizarre and not really sure how to approach this.... Every evening at exactly 11:10 pm the entire server "freezes". I can't get into the server, internet is down - there is no way to communicate with the server. I just dies - I have never seen that before. There were a few updates a few days ago and that is the only thing that has changed. The only solution is to reboot the server but I have to use the power switch to get it to shutdown ..... last night it triggered a parity check (previous 2 nights it did not). This has been going on for 3 straight nights with no end in site. Equipment: Dell R710 2U rackmount server Onboard 4 port NIC 23 HT’s and 46G memory Unraid server with various dockers such as Nextcloud, NZBGet, Sonarr and Bitwarden Server is stable and functioning as expected. PF Sense running on a VM using 2 of the 4 internal NIC's It has been really stable for the past 6 to 8 weeks. No sign of trouble. I did look at all the logs for the dockers, all cron jobs and found nothing except: Duckdns Docker Log at approx. the same time as the "outage" Something went wrong, please check your settings Sun May 17 23:10:05 EDT 2020 [s6-init] making user provided files available at /var/run/s6/etc...exited 0. [s6-init] ensuring user provided files have correct perms...exited 0. [fix-attrs.d] applying ownership & permissions fixes... [fix-attrs.d] done.

[cont-init.d] 10-adduser: executing... usermod: no changes Only thing I have found remotely close to the same time. I am out of ideas as to what is happening and am looking for some direction on where to look next. I will peruse the jobs that Sonarr and Radarr launch but no expecting much. Any and all suggestions welcome. Thanks in advance. Cheers.
May 18, 20206 yr Set up the syslog server (https://forums.unraid.net/topic/46802-faq-for-unraid-v6/page/2/?tab=comments#comment-781601) to mirror to the flash. Then wait and afterwards post the resulting syslog, along with a set of diagnostics
May 18, 20206 yr Author Ok thanks muchly. I have set up a syslog server on my windows PC and await 11:10 pm. I figure that is the best way to receive and process the entries. Good catch - I had no idea this was possible. Thanks Cheers Edited May 18, 20206 yr by toolmanz
May 19, 20206 yr Author Well I have solved the issue - didn't happen last night. I only changed a couple of things on the server and my network infrastructure - not sure what solved it. This is what I did before the appointed hour: 1. Updated some backend software on the Unraid Server 2. I stopped my Netdata docker because of how it was running it was highly suspect. 3. I removed an old router from my infrastructure that has caused problems in the past: dropping internet unexpectedly; certain ports messed up access; the reason I moved to PF Sense as speeds were extremely slow over fibre internet (getting 50 mbps when I should be getting at least 500mbps); when used as main router it would glitch out regularly. I think it is option 3 but not prepared to test it ..... I will however offer it up to the God of Routers and burn it on the alter of internet speeds mwahahaha. Sorry I digress. Lesson learned: Don't just expect that it is a software problem .... it might be hardware! Cheers
