July 19Jul 19 I'm not sure when this started but I've noticed my logs just spamming missing question.png file and some not all docker apps the missing icon flashes constantly. Any ideas on how to fix it?Thanks!unraid-diagnostics-20260719-0806.zip Edited July 19Jul 19 by Fiala06
July 20Jul 20 Community Expert Does rebooting solve the issue? If yes, there's a bug report about that happening for a few users.
July 20Jul 20 Hi,I also have this. maybe you want to look at /var/log/nginx/error.log.

July 21Jul 21 Author Thanks, I've been playing with it and just did a user script as a temp fix and seems to work. #!/bin/bash SRC=/boot/config/question.png DST=/usr/local/emhttp/plugins/dynamix.docker.manager/images/question.png [ -f "$SRC" ] && [ ! -f "$DST" ] && cp "$SRC" "$DST"
July 21Jul 21 I raised an issue and a PR for this on the Unraid Webgui github last week.Hope it gets a look at soonhttps://github.com/unraid/webgui/pull/2693@elibosley any chance you can find the time to look at this small PR? This issue is getting reported more and more in Discord as well. Edited July 21Jul 21 by chodeus

July 23Jul 23 just ran into this myself.. only noticed when i realised my "log filesystem" was showing red status at 100%. Thank you for highlighting it and raising the issue for investigation

July 31Jul 31 Could you stop pushing updates to dynamix.docker.manager until you fix this at the OS level? I am tired of having to fix this after every single plugin update. Edited July 31Jul 31 by cprn.1337
August 7Aug 7 I tried the temporary solution to copy the question.png to the folder but it keeps removing itself. Dunno why but I just downgrade to 7.3.1.

August 13Aug 13 I have several symptoms happening at the same time, and not sure if they are related:1) Docker icons flashing (presumably the question mark).2) Same ""/usr/local/emhttp/plugins/dynamix.docker.manager/images/question.png" failed (2: No such file or directory) while sending to client" in the log.3) Unraid API error. Restarting API doesn't work.4) Plug-in Check via "Check for Updates" doesn't show progress.5) I was barely able to download diagnostics.I'm going to reboot. tower-diagnostics-20260813-1618.zip
August 16Aug 16 Same issue as reportedBut also resulted in /var/log hitting 100% usage and log files failingI had to truncate both my syslog and nginx logI can see it's been fixed ready for 7.3.3 but it'd be really nice if we could get the fix without waiting for the next upgrade.

August 23Aug 23 Thank you to everyone in this thread for identifying the solutions to this issue. Thanks especially to @qinguan for hosting the default image to make this a simple one-liner for those coming up later.Just as an FYI for future readers before this is patched, you can pull the PR as a plugin that was compiled automatically here as well and install it that way, or run the commands listed in this thread.https://github.com/unraid/webgui/pull/2693
