    <description>&lt;P&gt;&lt;SPAN&gt;There are problems occurring when there are multiple TACs running.&lt;/SPAN&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;H3&gt;&lt;FONT color="#339966"&gt;&lt;STRONG&gt;Cause&lt;/STRONG&gt;&lt;/FONT&gt;&lt;/H3&gt;
&lt;P&gt;The issue may arise due to the TACs sharing the same port, resulting in conflicts between them.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;H3&gt;&lt;FONT color="#339966"&gt;&lt;STRONG&gt;Resolution&lt;/STRONG&gt;&lt;/FONT&gt;&lt;/H3&gt;
&lt;OL&gt;
&lt;LI&gt;&lt;SPAN&gt;Check if the problem occurs when you are running only one TAC. &lt;BR /&gt;If there are no issues when running only one TAC, it is highly likely that the issue is not related to Talend's product. There may be issues with the architecture, which is beyond the scope of Qlik's technical support team. Please consult with our Sales team or CSM (Customer Success Manager) team.&lt;/SPAN&gt;&lt;/LI&gt;
&lt;LI&gt;&lt;SPAN&gt;Do you have multiple TACs running on the same server or environment?&lt;BR /&gt;It is not recommended to have multiple TACs running on the same server or environment, as it may cause issues.&lt;/SPAN&gt;&lt;/LI&gt;
&lt;LI&gt;&lt;SPAN&gt;If you have an HA setup, please check that the HA setup is configured correctly.&lt;BR /&gt;For further details, please refer to the documentation: &lt;A href="https://help.qlik.com/talend/en-US/installation-guide-linux/8.0/setup-ha" target="_self"&gt;Setting up High Availability&lt;/A&gt;.&lt;/SPAN&gt;&lt;/LI&gt;
&lt;/OL&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;H4&gt;&lt;FONT color="#339966"&gt;&lt;STRONG&gt;Environment&lt;/STRONG&gt;&lt;/FONT&gt;&lt;/H4&gt;
