Why does subversion hang without any information?

Question

I tried to update some svn directories. But suddenly svn hangs without any output message.

I pressed ctrl-z and did a ps aux | grep svn. The svn process is hanging with SL.

What to do now? How to gain some error output?

I already tried to checkout some other repository, but this ended up in the same behavior.

Here is a full ps aux | grep svn:

I just had a talk to a Linux expert who was inhouse for a while. He had a look to this issue and solved the problem. Here is what I understood so far:

He made a strace to the svn up call which showed that the process was hanging while polling for some file on D-Bus. This file has something to do with Ubuntu's keyring. After disabling the password store in the subversion config everything working pretty fine.

To disable the password store I used these instructions:

Edit the ~/.subversion/config with gedit or nano , and add the following

[auth] 
password-stores =

then save and try again.
