<pre>I am trying to track down a memory leak that was triggered by a patch I wrote for my local copy of kamailio 4.1.4 . For this, I am following the documentation at <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory">http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory</a> . This page claims that once
memlog is set in the configuration file, a kamailio process will dump a report of the allocation map when shutting down, or when receiving a SIGUSR1. I have configured my kamailio.cfg with memlog=1 and no other change, and I see the memory report on
shutdown for all processes. However, when I send a SIGUSR1 to a kamailio process, the process does absolutely nothing, with the exception of the first kamailio process (the one reported as Type=attendant by "kamctl ps"). All of the other processes just
ignore SIGUSR1. What is going on? It is inconvenient to force a shutdown of all the kamailio processes just to get the memory report.
</pre>

<br>
From examination of the source code, I see that the disabling of
memory dumps on SIGUSR1 for child processes other than the main one
is not a bug, but a design decision. Why?<br>
