It looks like your mount.davfs process crashed. Most probable reason: out of memory.

davfs2 needs same hundred bytes of working memory for every file and directory it learns to know. It will not release this memory unless the file is deleted and davfs2 can see that it is deleted. So if you are running davfs2 for a long time and your repository is great then davfs2 might eat up all of your memory and finally crash without error message.

You can try option "minimize_mem 1" to avoid this. davfs2 will then from time to time scann all the remembered files and delete those that have not been in use for some time. Please read "man davfs2.conf" for details.

Please also read the information in the secrets file about how entries should look. It is "mountpoint username password".

Hello, I have a davfs mount which goes into this weird state in a few days. The permissions go all weird - ???????.
And I am not able to unmount or remount the drive after that. The only solution is a restart.

Attaching screenshots for weird state and what happens when I try to remount it.

I mount using the command -
sudo mount -t davfs URL_OF_DRIVE /mnt/firmware-artifacts

I am using the /etc/davfs2/secrets file, the last line on which looks like -
"URL_OF_DRIVE username password"

I have also edited /etc/updatedb.conf and included the /mnt/firmware_artifacts path into PRUNEPATHS, AND add davfs and davfs2 into PRUNEFS. This way the mount does not try to index the entire drive.

This problem is breaking my mount every week. Not sure what am I doing incorrectly.
