<h4 class="subsection">5.1.11 &ldquo;Cannot insert breakpoints&rdquo;</h4>
<p>If you request too many active hardware-assisted breakpoints and
watchpoints, you will see this error message:
<!-- FIXME: the precise wording of this message may change; the relevant -->
<!-- source change is not committed yet (Sep 3, 1999). -->
<pre class="smallexample"> Stopped; cannot insert breakpoints.
You may have requested too many hardware breakpoints and watchpoints.
</pre>
<p class="noindent">This message is printed when you attempt to resume the program, since
only then <span class="sc">gdb</span> knows exactly how many hardware breakpoints and
watchpoints it needs to insert.
<p>When this message is printed, you need to disable or remove some of the
hardware-assisted breakpoints and watchpoints, and then continue.
