Known issues
Out of date plugins
Out of date plugins can cause problems, we recommend they be kept current.
Docker fork bomb
A broken or maliciious Docker container can use all available Process IDs on the system, leading to instability. We are testing a fix in Unraid 7 and will backport it to a future release of 6.12. If you suspect you are affected by this, a workaround is to limit the number of PIDs a container can use by adding --pids-limit 2048 to the Docker template Extra Parameters setting.
Call traces and crashes related to macvlan
If you are getting call traces related to macvlan (or any unexplained crashes, really), as a first step we recommend navigating to Settings > Docker, switching to advanced view, and changing the Docker custom network type from macvlan to ipvlan. This is the default configuration that Unraid has shipped with since version 6.11.5 and should work for most systems.
Note that some users have reported issues with port forwarding from certain routers (Fritzbox) and reduced functionality with advanced network management tools (Ubiquity) when in ipvlan mode. If this affects you, see the alternate solution available since Unraid 6.12.4.
Network problems due to jumbo frames
If you are having network issues of any kind, confirm that you have not enabled jumbo frames. Navigate to Settings > Network Settings > eth0 and confirm the Desired MTU is 1500. For more information see the Fix Common Problems warning for jumbo frames.
Problems due to Realtek network cards
Upgraded kernel fixes the deadlock issue with jumbo frames and the in-tree Realtek 8125 driver. However, we still recommend following the advice above regarding jumbo frames.
If you continue to have network stability issues and Tools > System Devices shows that you have a Realtek ethernet controller, grab the part number shown and search Community Apps to see if there is a Realtek vendor-supplied driver plugin for that device. For more information, see the support page for Realtek driver plugins.
Other issues?
We highly recommend installing the Fix Common Problems plugin as it will warn you of common configuration problems.
If you are having other crashes or stability issues, navigate to Settings > Syslog Server and enable Mirror syslog to flash. This will cause additional wear and tear on you USB flash boot device but is useful in the short term for gathering logs after a crash.
After the next reboot, navigate to Tools > Diagnostics and download your anonymized diagnostics (as of 6.12.5, diagnostics automatically include logs that were mirrored to the flash drive).
Finally, start a new topic under General Support and provide all the details of the issue. Once the issue is resolved, be sure to disable Mirror syslog to flash.
Rolling back
If rolling back earlier than 6.12.10, also see the 6.12.10 release notes.
