<p>Hi,</p>
<p>The warning/error</p>
<p>pthread_setschedparam failed: Not owner</p>
<p>is also happening on Solaris, and obviously it also prints some text,<br>
which does not really make sense on Solaris.</p>
<p>I have documented on the following Wiki how to get rid of this warning/error<br>
on Solaris:</p>
<pre><code>    https://sourceforge.net/p/solaris-squeak/wiki/Home/
</code></pre>
<p>I don't know how to fix the issue specifically on your Ubuntu distribution,<br>
but possibly it makes sense to - when the error happens - to print a simple:</p>
<p>"error: pthread_setschedparam failed: Not owner</p>
<p>or</p>
<p>"error: heartbeat thread unable to run at higher priority"</p>
<p>Such a simple short message would be sufficient, and then the user can<br>
try to do some research and find fixes for the specific platform,<br>
where the error happens.</p>
<p>I can imagine that on various Unix flavors the instructions for:</p>
<p>/etc/security/limits.d/squeak.conf</p>
<p>do not apply.</p>
<p>Also note that in my limited experience on Solaris, I can either fix<br>
the warning (by having threads run at different priorities) or ignore<br>
the warning, as it does not seem to make much difference ...</p>
<p>But it's not nice that an extensive error message is printed,<br>
certainly not when it does not apply to that specific Unix distribution.</p>
<p>Regards,<br>
David Stes</p>
