Can someone help me debug this issue? Everything works (i.e. I can commit, checkout, etc.) but this one commit always fails as described below. I tried checking out in a new repository, and committing, but same issue. Note also that this is a very large repository (500GB), and a very large commit (36k files totaling 10GB).

This is the `apache2` error log:

    [Sat Feb 10 03:25:16.262765 2018] [dav:error] [pid 3339] [client X.X.X.X:61908] Could not DELETE /svn/repo/!svn/txn/463-e8.  [500, #0]

The client side gives:

    Committing transaction...
    svn: E175012: Commit failed (details follow):
    svn: E175012: Connection timed out
    svn: E200042: Additional errors:
    svn: E175002: Unexpected server error 500 'Internal Server Error' on '/svn/repo/!svn/txn/463-e8'

First I thought this was a permission issue. So I did this on the server:

    su - www-data -s /bin/bash -c "svnadmin rmtxns /mnt/vc/svn/repo/ 463-e8"
    Transaction '463-e8' removed.

No error whatsoever. Apache runs as `www-data`. Following permissions are set:

    chown www-data:www-data /mnt/vc -R
    chmod 0774 /mnt/vc -R

I have run `svnadmin verify` and found no problems. `dmesg` doesn't show anything new.

The apache svn config is pretty much default.

    libapache2-mod-svn/stable,stable,now 1.9.5-1+deb9u1 amd64 [installed]
    Server svn client: 1.9.5-1+deb9u1 
    Client: svn 1.9.7

**EDIT:** I copied the working copy to the repository server. Then I tried to commit, but had the same error. I then relocated the working copy to direct repository location: `svn relocate file:///mnt/vc/svn/repo`. Commit worked this time. So it has to do something with `dav_svn`?

Yes, this is the correct place to report such an issue. But to
maximize your chances of people helping you, can you please copy the
relevant contents / context to the mailinglist here, instead of
forcing people to click a link?
