azmsgsync File name too long?

[drelephant]

Using BiglyBT 3.0.0.0 on Ubuntu 18.04.6 LTS (Gnome), often over VNC.

BiglyBT crashes every now and then, I still haven't worked out what's causing it but the GUI becomes unclickable and doesn't refresh the display.

Often I can still connect from the Android app when this happens however.

Not sure if it's related but I see a lot of errors on the console about filename too long:

How can I fix these errors and hopefully stop biglybt from freezing up?

Doesn't seem very long to me, do you have some lame file system?

I can't see how that error can be related to BiglyBT freezing. The usual cause of that is low Java VM memory, do you have a lot of active downloads? Check https://github.com/BiglySoftware/BiglyBT/wiki/Diagnostics for some info.

It's ext4 with encrypted /home, don't think that should make a difference though? I just ticked the box for encrypted home folder when installing ubuntu.

Definitely getting that error though, even from the command line: touch '/home/redacted/.biglybt/plugins/azmsgsync/save/IJUWO3DZIJKDUICJGJIDUICEJZJSARTFMVSFW4DLHVAVGM2XGJLUQRSHIZIU2RBSJNKTOWRSLFCDESKNLFEVUSRVKJDTGNCBK42FKUSQJNIFCN2OJJJEGWSLJJKTEUCEKI2ESR2HIVBUMTCKJVHVCTKBKJATOMSTIRFDIMSZEZZG6PJRLUp.dat.saving'

touch: cannot touch '/home/redacted/.biglybt/plugins/azmsgsync/save/IJUWO3DZIJKDUICJGJIDUICEJZJSARTFMVSFW4DLHVAVGM2XGJLUQRSHIZIU2RBSJNKTOWRSLFCDESKNLFEVUSRVKJDTGNCBK42FKUSQJNIFCN2OJJJEGWSLJJKTEUCEKI2ESR2HIVBUMTCKJVHVCTKBKJATOMSTIRFDIMSZEZZG6PJRLUp.dat.saving': File name too long

But I know ext4 is meant to allow 255 byte names and unlimited path size, so it's very odd.

edit: hmm, actually it's ecryptfs, didn't realize it would be different: stat -f -c %T /home/redacted/ ecryptfs

Edit: according to https://unix.stackexchange.com/a/32834/52247 if filename encryption is enabled, there is usually a limit of ~140 characters. Damn.

I just tested and the max filename length I could use is 143 chars.

Is there any way I can prevent biglybt from trying to write such long named files?

I have only about 10 active downloads?

I've fixed things if you join the beta program

OK great, just joined.

Thanks again!!
