My tor log file is usually quite boring but today it looks like this: Jun 14 13:42:46.000 [warn] Hash of session info was not as expected. Jun 14 13:57:56.000 [warn] Hash of session info was not as expected. Jun 14 14:11:58.000 [warn] Hash of session info was not as expected. A new line about every 10 minutes since 04:14:53 (CET) Is it a user with problems, an attack on my relay or a sign that my relay have some kind of hardware/software issues?
