Error opening database: resource temporarily unavailable

Support

Hi there,

I’ve got above error last days. Before all was fine. Syncthing is running under Ubuntu 24.04.

What I can do to solve that problem?

Thanks in forward Rico

There’s not enough details to really diagnose much, so if nothing else changed related to Syncthing before the error appeared, use the following command to view the kernel messages for possible alerts about filesystem errors:

dmesg -T

Next, see the Syncthing Configuration documentation page for pointers to where your Syncthing database is. Check the directory to see if there are any obvious issues such as permissions, etc.

verbatim / unaltered copy-paste Syncthing logs would also be a helpful, even simpler start.

The log shows the following …

I couldn’t find any errors in the kernel log.

This is the usual cause.

oops, I read it but ignored it:

pidof syncthing
# 2379 2338

What can I do, which process should I delete now?

ok, now it’s working. I have deleted both processes and restarted syncthing. Thanks
