<p>Hi Matt,</p>
<p>The only time I've seen strace "crash" ganesha is when having selinux enabled which ofc was related to selinux.</p>
<p> </p>
<p>Have you also changed NFS's logging level (also in the link given)?</p>
<p>Check the current level with:</p>
<pre class="pre codeblock"><code>mmnfs configuration list | grep LOG_LEVEL<br /></code></pre>
<p>I find INFO or DEBUG enough to get just that little extra nugget of information you need, however if that's already at FULL_DEBUG and your still not finding anything helpful it might be time to log a PMR.</p>

se is disabled here.<br /> Also if you strace the parent ganesha.nfsd process it dies. Is that a bug?<br />
