Parent response did not contain a site version in Relay Logs

I’ve read a lot of posts and tried to troubleshoot these errors myself but seem to continually see them appear in our T1 relay logs.

I’ve attempted to replace the masthead, I’ve done a GatherState reset and tried various other troubleshooting steps but just can’t get them to vanish.

Anyone got any ideas?

I did find it interesting thought that the besgathermirror.exe was also listed as BESGatherMirror.exe (caps in places) - not sure if that’s the norm or a code problem?
