What do those yellow horizontal arrows in eclipse, at the left of the line numbers do?

Question

I'm talking about the lines that are in the same visual space as my break points. What do those do, and why are popping up and covering my break points?

I am in the Java perspective, i'm looking at the code (code editor view), the debugger is not running, my application is not running. My eclipse is Helios. and I've got RTC tools installed on it.

Thx, you guys are awesome.

EDIT: arrows are not triangles. I wasn't talking about the warnings :P

EDIT #2: a snapshot added:

Answer 1

The yellow arrows show up next to search results for me. If you go to the search tab and delete the results they should go away.

Answer 2

You can get rid of them by going to Preferences > General > Editors > Text Editors > Annotations, then look for "Search Results" and uncheck "Vertical Ruler".
