When I try to create a sub-folder under the “tags” folder, the operation always takes about 2-3 minutes and ultimately returns with an error:
MERGE of '/development/tags': timed out waiting for server (http://<server IP address>:<port>)

I have tried creating the sub-folder from TortoiseSVN as well as from SVN command-line and I see the same result.

The same operation is successful under “branches” or “trunk” and the new sub-folder is created within a few seconds.

Here is my environment:
SVN server (uberSVN) runs on a Windows 2008 server machine.
I use SubversionNotify for basic hook operations (a pre-commit check to ensure that there is a log message with every commit and a post-commit operation that sends emails to developers on every commit).
There is no mention of the “tags” folder in my SVNNotify configuration file. All the settings are applied to the repository root and one of the braches.

I have also looked at the SVN and Apache logs and did not find anything relevant.

Please give me some ideas to head in the direction of a resolution for this issue.
