"svn commit" hangs -> select(0, NULL, NULL, NULL, {0, 25000}) =
0 (Timeout)
Hello,
"svn commit" does not work anymore for a project with the repository on
my computer. Another project on an other server using svn is still
working. So I think svn can't be broken but the database has to?
After running the command "svn commit" vi pops up and I can write the
log. But after exiting the editor nothing happens.
strace shows me where svn is hanging:

The last lines are repeating continuously. What is the problem? Is the
database broken? If so, what can I do to rebuild the database?
Checking out a fresh project and doing a "svn commit" leads to the same
error.
Thanks & regards,
Alexander

Ah thanks, that's it! 'svnadmin recover' has recovered the database and
now it's running again.
Thank you very much!

It would also be helpful to mention that you're using the BerkeleyDB FS
backend, and tell us which repository access mechanism you're using
(given strace output and "on my computer" comment, ra_local?).

You're able to open the DB here.

...and map it into memory here.

Waiting for activity on stdin.

It's not clear that there's actually a problem with your DB. You could try
'svnadmin recover' to confirm that (this is mentioned in the book).
Does your commit work if you explicitly pass the log message via the -m or
-F flag? Are you sure you have write permission to the location that you're
running 'svn commit' from (so that your log message can be saved)?
