On a similar note, I have been using FISH as a replacement for ages, since I
was also affected by this bug, but apparently I can no longer reproduce any
SFTP hang with a couple of hosts.

Quite some time since I tried it last time, I only used sshfs since.
Apparently, the problem is gone. I can now login to a sftp host again using
Dolphin. I have currently Plasma 5.17.5 and Frameworks 5.64.0 installed.

But it's also another new machine, so ... whatever. It works again now ;-)

Still a problem?

Have you tried moving your .ssh out of the way so you start with a pristine
config?

If you feel comfortable with gdb I think the best way to debug this is to
attach gdb to one of the 100% processes and backtrace them. They are very
likely stuck doing something, if we knew what it is they are stuck on we'd
probably have an easier time figuring out what causes it.

... and it's also still the same here with 18.12.0. When I'm trying to
establish an sftp connection, I get multiple sftp.so processes cosuming 100 %
CPU (or as much as they can get).

Please re-test with 18.08.3 and libssh-0.8.x, we have backported all the
changes to sftp from 18.12 branch.

you may also need to logout and login or at least run kbuildsycoca.

Tobias: you can try bisecting your home directory - possibly in a new user -

I'm still trying to track this down. I moved ~/.local and ~/.config, but it
didn't help. I'm still seeing the same error. If I remove the respective line
from ~/.ssh/known_hosts, I get the question if I want to connect to the host,
but It's the same afterwards.

So: Which .* files are affected by this?!

I simply want to avoid killing my whole home directory ...

strace outputs tons of whatever when I start up Dolphin ... I really can't find
something in there ...

But I found something in ~/.local/share/sddm/xorg-session.log:log_kio_sftp,
which is probably interesting:

log_kio_sftp: file system free space of QUrl("sftp://some_server/;)
log_kio_sftp: checking cache: info.username = "" , info.url =
"sftp://some_server;
log_kio_sftp: Creating the SSH session and setting options
log_kio_sftp: Trying to connect to the SSH server
log_kio_sftp: username= "" , host= "some_server" , port= 22
log_kio_sftp: Trying to authenticate with public key
log_kio_sftp: Getting the SSH server hash
log_kio_sftp: Trying to authenticate with public key
log_kio_sftp: Checking if the SSH server is known
log_kio_sftp: Trying to authenticate with the server
log_kio_sftp: Getting the SSH server hash
log_kio_sftp: Checking if the SSH server is known
log_kio_sftp: Trying to authenticate with the server
log_kio_sftp: Trying to authenticate with public key
log_kio_sftp: Trying to authenticate with public key

After all, the question is: How can this happen with an existing user without
changing any configuration? As we know now, there's no problem with a new user
...

Try using strace. Otherwise, i am not an expert.

My DE is KDE (obviously ;-)

I didn't try yet to use a new user. It actually does _not_ happen with a new
user! Which is actually very interesting, isn't it?

I tried to remove the passwords from kwallet, but the error still occurs.

Can you give me a hint what config file I have to delete/modify to get a
"clean" sftp reset, so that I don't have to delete my ~/whole KDE config?

Thanks a lot for helping me to track this down! I really didn't think it was a
config issue (because I never changed anything, the error "simply" emerged)!

I see.

1. What is your desktop env?

2. Does it happen in a new user?

3. Can you try strace?

Same thing btw if I try to access the server using KWrite, with the difference
that only two sftp.so processes are started. So, probably, this is not a
Dolphin problem.
