Just FYI, CSP sessions are instances of %CSP.Session. You could do ##class(%CSP.Session).%OpenId("wuuZ2Gwgxw") to get the session and use some of the properties and functions there to get more information on what's going on. And since they extend %Persistent, you can also use %DeleteId (at your own risk, of course).

If you are looking for the class name where a currently-running method originates, you could also try:

	set method = $CLASSNAME($THIS)_"||"_$P($Stack($stack,"PLACE"),"+",1)
	&sql(select Origin into :origin from %Dictionary.CompiledMethod where ID1 = :method)
	w origin,!

Are you trying to get all of the classes that a class extends? You can do that like this:

	set classname = $CLASSNAME($THIS)
	&sql(select primarysuper into :super from %dictionary.compiledclass where id=:classname)
	w super,!

If you do that, super is a ~ separated list of the class and everything that it inherits from, which is probably actually more information than you need.
