@snack You need to install & activate https://wiki.archlinux.org/title/Debuginfod to get debug symbols for the libraries that seafile-daemon uses. Then you can try run the same coredumpctl cmd again, but this time there should be proper function names instead of ()

After months of working with no problem the issue with seaf-daemon crashing on start happened again this morning. I paste below the debug output. @bionade24 do you see anything useful in it?

Edit: I forgot to mention that I freshly rebuilt libsearpc, seafile and seafile-applet before doing the test.

@snack: Rebuild the package with debug symbols and if it afterwards crashes again, run coredumpctl debug seafile-daemon and then bt and post the output here. This will help much more than asking if others have the same issue. https://wiki.archlinux.org/title/Debugging/Getting_traces#Rebuild_packages

Since version 8.0.10 I get a strange behavior. After upgrade to 8.0.10 everything seemed to work correctly, but after a restart of seafile-applet none of my libraries was synced anymore. This is due to seaf-daemon continuously segfaulting. I had to delete ~/Seafile/, restart seafile-applet and re-sync everything. But after another restart of seafile-applet the problem came up again. I downgraded to 8.0.9 and now everything seems OK again.

It looks like seaf-daemon 8.0.10 has a bug that makes it mess with something on shutdown, which in turn makes it segfault at the subsequent restart, and that it works only with a pristine configuration. Does anybody experience the same?

in this version maybe need to make openssl-1.1 as dep too

Hi, I have the same issue as centaurefox. After rebuilding libsearpc I get the rror: ModuleNotFoundError: No module named 'pysearpc'

You have to rebuild libsearpc to fix the ModuleNotFoundError.

I can reproduce the issue pointed by Centaurefox
