This suggests that reload wasn't successful for some reason.<br>
<br>
There are various legitimate cases when reload might fail even if <br>
the configuration is perfectly correct: for example, if there are <br>
conflicting settings for a shared memory zone (e.g., you cannot <br>
change size of a shared memory zone), or when using conflicting <br>
listening sockets on Linux (such as "listen 80;" and "listen <br>
<a href="http://127.0.0.1:80" rel="noreferrer noreferrer" target="_blank">127.0.0.1:80</a> bind;"). Detailed information about why reload <br>
failed is expected to appear in the error log.<br>
<br>
Further, bugs in 3rd party modules might additionally break <br>
configuration reloads. If there are any, you may want to test if <br>
things work correctly without 3rd party modules.<br>
<br>
Hope this helps.<br>
