========================================
<p>In the late afternoon shifters noticed the semi-expert drive GUI was not updating, several restarts did not help. Checking into the issue with the drive team connecting from remote it was found that the MOS server is not running and cannot be restarted. This issue could not be solved and will be revisited tomorrow, Jan 17, during the day.</p>

<p><em>Actions applied for solving this issue: (T. Le Flour)</em></p>

<p><em>The status is the following</em></p>

<ul>
	<li><em>The MOS OPCUA Server cannot be relauched since the port used by server was not properly released after the last stop.</em></li>
	<li><em>We decided to reboot the VM running on TCS02 but after this operation , the concerned port was still in use.</em></li>
	<li><em>By using the commend lsof , we relased the port and relaunched successfully the server.</em></li>
	<li><em>Actions : releasing the port has been included in the script used to launch the server to prevent such an issue.</em></li>
</ul>
