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

&lt;p&gt;When running this through mongo shell on mongos, I don&apos;t see wtimeout showing up when I turn on high COMMAND verbosity on mongod on prepareTransaction and commitTransaction.&lt;/p&gt;

&lt;p&gt;So if we kill two nodes in a 3 node shard, then we will observe that the prepareTransaction / commitTransaction blocks indefinitely, since that is the default value of wtimeout.&lt;/p&gt;

&lt;p&gt;This is not the case if I run the above statements on a replica set (although the value of wtimeout used when committing is from startTransaction).&lt;/p&gt;

&lt;p&gt;Wtimeout is honored when running individual operations on a sharded cluster. For example, I see that a single insert operation with a &lt;tt&gt;w&lt;/tt&gt; and &lt;tt&gt;wtimeout&lt;/tt&gt; value has the writeConcern values respected.&lt;/p&gt;</description>
