<div>Thanks Bob,</div>

<div>I just tried that and indeed, after doing that and a
GC, it removed almost all garbage I have around and
indeed, it called all the #unregistered of my sessions. </div>
<div>So.... OK, with such code I can at least force the GC
of those (which is similar to the one I was doing: <b style="font-size:12.8000001907349px">WAApplication
allInstances do: [ :each | each clear ].)</b> ,
but... I still wonder, why my sessions are not "reap"
automatically? Why they do not get the #unregistered
automatically? From what I understand, they should,
right?</div>

<div dir="ltr">Hi guys,
<div><br>
</div>
<div>I am having a hard time to see why my
seaside sessions are not being GCed nor
unregistered. </div>
<div>First of all, when I register my app, I set
a timeout. I even tried with 1 minute timeout:</div>
<div><b><br>
</b></div>
<div><b>app cache expiryPolicy configuration at:
#cacheTimeout put: 60</b></div>
<div><br>
</div>
<div>I put a <b>halt in MySessionSubclass
>> #unregistered</b> (which then calls
super).</div>
<div><br>
</div>
<div>I have seen many seaside things around:</div>
<div><br>
</div>
<div>
<div>WARenderVisitor instanceCount -> 77.</div>
<div>WAHtmlCanvas instanceCount -> 1061.</div>
<div>JQueryClass instanceCount -> 13492.</div>
<div>WACallbackRegistry instanceCount ->
77.</div>
</div>
<div>MySessionSubclass -> 12.</div>
<div>.....</div>
<div><br>
</div>
<div>As you can see, I have plenty of memory
around callbacks registries, renders,
visitors, sessions etc... If I try to see
which sessions were expired:</div>
<div><br>
</div>
<div>
<div><b>MySessionSubclass allInstances select:
[ :each | (each instVarNamed: 'parent')
isNil ] -> #() </b></div>
</div>
<div><br>
</div>
<div>The 'parent' instVar there is because
"super unregistered" does that and I don't
know another way to check if a session is
expired or not.</div>
<div><br>
</div>
<div>Finally, the only way I have to get rid of
everything is this way:</div>
<div><br>
</div>
<div>
<div><b>WAApplication allInstances do: [ :each
| each clear ].</b><br>
</div>
<div><span style="white-space:pre-wrap"><br>
</span></div>
<div><span style="white-space:pre-wrap">But
then, that clears all sessions...even the
active ones which I don't want. <b>So....
how can I force the GC of all none
expired sessions? And why my sessions
are not receiving #unregistered ?</b></span></div>
</div>
<div><span style="white-space:pre-wrap"><b><br>
</b></span></div>
<div><span style="white-space:pre-wrap">Note
also that in my example the instanceCount of
MySessionSubclass is bigger than 10, because
somewhere I read that Seaside would start
cleaning sessions upon 10th. </span></div>
<div><span style="white-space:pre-wrap"><br>
</span></div>
<div><span style="white-space:pre-wrap">So....
any idea? What am I doing wrong?</span></div>
<div><span style="white-space:pre-wrap"><br>
</span></div>
<div><span style="white-space:pre-wrap">Thanks
in advance, </span></div>
