<p class="MsoNormal">We are running stunnel 5.49 on FreeBSD 11.2 and we’re running into a problem once in a while.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">CPU pegs at 100% when we get an stunnel connection from one of our external devices.
<o:p></o:p></p>
<p class="MsoNormal">This affects 100% of all cores and we can’t even log in to console.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To mitigate this temporarily, we have a script running in the background to watch when stunnel begins to spike and restarts the daemon.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It doesn’t happen 100% of the time, and so far I have been unable to distinguish what makes the connection do this to the CPU.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Have any of you run in to this issue? <o:p></o:p></p>
