Description

As you can see the sid 2012100 is not loaded, and at the log there's no line information:
"from file /opt/ruledump/suricata/open/all.rules at line\n"

The error of the sig I guess it's related to the first content, that's followed by distance without having a previous content.

My guess the info is omitted because of an internal limit in the output code... some max line size or similar...

Why 1280? If there is no special reason I'd like to increase some more, like 2048 or 4096. Or is there some drawback to that?

No reason. You can increase it if you like.
