Bug description:
  I am using Apache2 with client certificate authentication.
  Since recently (last week) and without any configuration changes, the following errors occur frequently:

  AH02042: rejecting client initiated renegotiation

  Client connections are very slow and sometimes it takes more than a minute until a weg page can be opened in the browser.
  Before installation of the latest security fixes last week, this error did not occur.

  Could it be related to
