Bug #413

Updated by Sven Eckelmann almost 2 years ago

It was reported that some installations with enabled OGMv2 aggregation can cause the own originator to appear in the originator table via a different node:

<pre>
My originator messages look wrong as I can see my host originator messages along with all the neigbor nodes:

Disabling aggregation seems to solve this problem.
