Resolving Syslog Spam with 'emhttpd: *** bug: 57' Messages in Syslog

Featured Replies

Hello everyone,

 

By chance, while configuring the NUT server today, I noticed the syslog and found that three messages are being spammed continuously multiple times per second.

Oct 5 10:54:38 Tower emhttpd: *** bug: 57 /mnt/user/system cache
Oct 5 10:54:39 Tower emhttpd: *** bug: 57 /mnt/user/appdata cache
Oct 5 10:54:39 Tower emhttpd: *** bug: 57 /mnt/user/domains cache

 

Apart from that, the system is actually doing well. I haven't noticed any problems or instability. Could you please explain what the issue is and how I can fix it?

That happens when shares have an invalid config, click on each of those shares and correct primary and secondary storage locations.

Thanks for the reply JorgeB! 
I clicked on the different shares and compared the ones with errors to those without errors, and they look quite similar to me. Could you please provide more insight into what might be wrong here?The secondary storage is always set to none, and the primary is the array with all disks.

System share for example is set to:

 

shareUseCache="prefer"
shareCachePool="cache"

 

And cache pool no longer exists, maybe v6.12 doesn't show that, v7 would, but try just reapplying those settings and post new diags

Could you please guide me with a bit more details?
I can't find a place to set these settings. But what I did find is this cache folder and I have no cache drive installed in my system. Do I maybe just need to remove this folder?Bildschirmfoto2024-10-05um14_39_50.thumb.png.f8f214488b36e4f1c55c1f86add27a63.png

Try just doing a dummy change on the share settings, then click apply, that should update the settings.

Thank you for the clarification, done with all 3 shares!

When I run Fix Common Problems now, I see one more issue besides 'Invalid folder cache contained within /mnt', which says that 'Default docker appdata location is not a cache-only share'.
How can this be?

I would first reboot to see if it reappears.    If if it does that most likely means you have a docker container with a mapping that starts /mnt/cache
