Hi, I also have received the same error for the last few weeks sometimes. I was able to solve it with this command after looking into the .err logfile 2022-01-05 23:39:32 0 [ERROR] mariadbd: Can't create/write to file '/var/tmp/ibXXXXXX' (Errcode: 13 "Permission denied") 2022-01-05 23:39:32 0 [ERROR] InnoDB: Unable to create temporary file; errno: 13 chmod 777 /var/tmp

Quick update: Since I disabled host access and moved all the bridged docker towards a separate vlan, I Haven't had a crash since then. Stable now for 25 Days. Still have a few of my dockers on host or default bridge, but this is running without any problems at the moment. @JorgeB, thanks for your suggestions and thoughts !!!

Just moved all of my proxynet dockers towards the br0.208 network and also disabled host access to networks in docker settings. curious if this stay stable now. luckily I'm well equipped regarding router and switches XD.

so you still suspect it has something to do with mac vlan (docker network) despite I already moved all dockers with static IP address towards an separate vlan on my network. could it be the proxynet network which causes this crashes then? otherwise I will move them towards the other vlan also but with a dhcp server active then in that vlan.

Follow, I too has this issue for a long time already. today unraid crashed again and also needed to stop and start docker separately before the containers were able to access each other again on the host.

Today unraid crashed again seems to me the issue today was with the ISCSI plugin?? so I deleted it. i attached the logs and diagnostics, maybe someone else sees something else which I cant find. unraid-crash-syslog.xlsx unraid-diagnostics-20210708-1912.zip

Thanks I just created an separate vlan for the dockers with a static ip address and migrated them toward it. let's see if this gives some stability again.

unfortunately still no solution from my side. it still happens randomly.

today it happend again I dont know the exact time, but I Suppose this belongs to the crash.

Hi All, Since I started using unraid I have regularly crashes ( once a 2/3 weeks or so ) Sometimes even more. Now I recently added the syslog towards my NAS, So now I am in possession of the logs before the crash. Server: Dell R630 2x 600GB SAS Drives Version: 6.9.0 If anyone has a suggestion what could be the reason of this random crashes. I would appreciate it. I've added the syslog entries as attachments. unraid-error..csv unraid-error.xlsx
