We have just released rsyslog 4.6.5, a member of the v4-stable branch.
This update addresses the TLS bug, that has been bothering a lot of users lately and a few other issues. It stops rsyslog from looping, thus disabling functionality and bearing the risk of unresponsiveness of the whole system. More details about this issue can be found here:
See ChangeLog for more details.
As always, feedback is appreciated.
