rsyslog error 2291

Error in RELP processing

If this message occurs:
imrelp: could not activate relp listner, code 10046

This means that the platform does not provide TLS auth support. In general, this means that GnuTLS is too old.

Here is the recommended solution:
Install a current version of GnuTLS on that system and rebuild librelp from source.

Alternatively you can try to use TLS in anonymous mode! Please note that this does not guard against man-in-the-middle attacks, it at least keeps message flow encrypted.
