SVN-KIT - svn: E140000: Can't read length line from file

SCM-Manager Bug Reports SCM-Manager
1

I have observed that the SCM-Manager would slowdown while managing the API-KEY based requests with the SVN clients.

  1. SCM-Manager: v2.3.40
  2. SVN-KIT: Default
  3. LDAP Integrated: YES
  4. LDAP CLient version: v2.4.0
  5. API-KEY Created: YES

It would try to check the LDAP authentication eventhough API-KEY is supplied.

How to reproduce:

  1. Create a SVN repository using the SCM-Manager WEB-UI
  2. Enable required permissions on the WEB-UI
  3. Restore the old repository using svnadmin load
  4. Check and fix the permission: chown -R scm:scm <repo_path>
  5. Check the scm-logs and we can see flooding logs as shown below.
  6. The flooding logs will hinder the SCM-Manager performance drastically forcing to restart within an hour

Note: I have also verified the same on APache+SVN-DAV without any issues and this indicates that the issue is specific to SVN-KIT

Hi @girishkg , this is hard to analyse without an example. Can you create a small repository with this issue, zip it and share it with us?
