<p class="MsoNormal">Thanks for your reply !<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For the record, I’m using Kamailio module "flatstore" with the flush deactivated. In this situation, when Kamailio is stopped, I’m losing the remaining data in files not yet flushed.<o:p></o:p></p>
<p class="MsoNormal">So my idea was, when destroy is called, to iterate over the connection pools, and flush/close all the opened files properly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But I found out that it’s not that simple :/<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Do you think this is something that could be fixed in Kamailio ?<o:p></o:p></p>

<p class="MsoNormal"><span lang="DE"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">you are right, there is no special function for children destroy. Most modules do not need it, as the data is in shared memory, processes are started over standard kamailio APIs which will be stopped from the core automatically,
to give some background.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Some modules do it by just iterating over an internal list of their children and then do the cleanup task. You can find an example in cdp module (destroy, diameter_peer_destroy).<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:35.4pt">I’ve looked at the "struct module_export", in which I see "mod_init", "child_init", "mod_destroy"… but no "child_destroy". :/<o:p></o:p></p>
