<p>When <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-zombie"><em class="xref std std-term">zombie</em></a> s arise they can be handled manually by <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-ecflowview"><em class="xref std std-term">ecflowview</em></a>. (See <a class="reference internal" href="/wiki/display/ECFLOW/Zombie#zombie"><em>Zombie</em></a>)
<strong>or</strong> via the command line interface:</p>
<ul class="simple">
<li>ecflow_client &#8211;zombie_get</li>
<li>ecflow_client &#8211;zombie_fail   &lt;task-path&gt;</li>
<li>ecflow_client &#8211;zombie_fob    &lt;task-path&gt;</li>
<li>ecflow_client &#8211;zombie_adopt  &lt;task-path&gt;</li>
<li>ecflow_client &#8211;zombie_remove &lt;task-path&gt;</li>
<li>ecflow_client &#8211;zombie_block  &lt;task-path&gt;</li>
</ul>
<p>However it is also possible to ask <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-ecflow-server"><em class="xref std std-term">ecflow_server</em></a> to make the same response in
an automated fashion. How ever <strong>very</strong> careful consideration should be made before doing this.
Otherwise it could mask a serious underlying problem.</p>
<p>The automated response can be defined with:</p>
<ul>
<li><p class="first">python interface( See <tt<a class="reference internal" href="/wiki/display/ECFLOW/ecFlow+Python+Api#ecflow.ZombieAttr" title="ecflow.ZombieAttr"><tt class="xref py py-class docutils literal"><span class="pre">ecflow.ZombieAttr</span></tt>tt></a>)</p>
</li>
<li><p class="first">text interface ( See <a class="reference internal" href="/wiki/display/ECFLOW/Definition+file+Grammar#grammer"><em>Definition file Grammar</em></a>)</p>
<div class="highlight-python"><pre>zombie             ::=  "zombie" &gt;&gt; zombie_type &gt;&gt; ":" &gt;&gt; *child &gt;&gt; ":" &gt;&gt; !(client_side_action | server_side_action) &gt;&gt; ":" &gt;&gt; !zombie_life_time
zombie_type        ::=  "user" | "ecf" | "path"
child              ::=  "init" | "event" | "meter" | "label" | "wait" | "abort" | "complete"
client_side_action ::=  "fob" | "fail" | "block"
server_side_action ::=  "adopt" | "delete"
zombie_life_time   ::=  unsigned integer  ( default:  user(300), ecf(3600), path(900)  )</pre>
</div>
</li>
</ul>
<p>The zombie attribute is inherited in the same manner as <a class="reference internal" href="/wiki/display/ECFLOW/Variable+inheritance#variable-inheritance"><em>Variable inheritance</em></a>.</p>
<p>Example: For tasks under suite &#8220;s1&#8221; add a zombie attribute, such that child label commands(i.e ecflow_client &#8211;label) never block:</p>
