At this stage I've posted this patch to say:<br>This seems to fix the error, does it seem reasonable/correct?</p><p style="white-space: pre-wrap; word-wrap: break-word;">I have traced out all +1/-1 references on subscription tree's, I have determined that sub_tree->root->tree is never released. I do not know if this is the correct place to release that reference.</p><p style="white-space: pre-wrap; word-wrap: break-word;">In the reference logs I've reviewed the ao2_ref(sub_tree, -1) below (Remove evsub's reference) is another one I'm not fully sure of. I believe evsub is holding the allocation reference? If that's the case I can add a comment to the subscription tree allocation routine.</p></li></ul></li></ul><p>To view, visit <a href="https://gerrit.asterisk.org/6857">change 6857</a>.
