Bug #7730
open2.3.4_1 greX: loop detected when hit save on filter rules or interfaces
0%
Description
upgraded from 2.2.6
anytime we hit save in the GUI for interface or filter rules, even if no change was made, we start getting Jul 25 14:50:02 <histname> kernel: greX: loop detected spam in dmesg/system.log. Our GRE tunnel goes down.
Any cluster sync activity from the Primary to Secondary also causes this issue.
We have to do a save on the GRE interface in the web GUI (this downs/ups the interface) and the tunnel starts working again.
