            <title>[SERVER-48705] resmoke.py sending SIGABRT to take core dumps on fixture teardown may overwrite core files from hang analyzer</title>
                <link>https://jira.mongodb.org/browse/SERVER-48705</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When archival is enabled for a test or test suite, resmoke.py sends a SIGABRT signal to its fixture processes to take a core dump of them (in addition to collecting the mongod data files). If a JavaScript test has already invoked the hang analyzer via an assert.soon(), then the core file generated from the hang analyzer will be overwritten.&lt;/p&gt;

&lt;p/&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Note that the core dump taken by resmoke.py sending a SIGABRT signal is unlikely to match the thread stacks in the hang analyzer output because running the hang analyzer is expected to perturb the state of the MongoDB cluster.&lt;/p&gt;</description>

&lt;p&gt;Adds an option to the hang-analyzer to kill processes after finishing analysis.&lt;br/&gt;
Updates assert.soon&apos;s usage of the hang-analyzer to use this option.&lt;br/&gt;

We can ask the shell to SIGKILL all its fixtures after calling the hang analyzer so the archival code does not have to do it later on.&lt;/p&gt;</comment>
