Hmmm... where is performAction?
WODirectAction, you might have to manually override it in DirectAction.
I have the following in Application:
public WOResponse handleActionRequestError(WORequest aRequest,
Exception exception, String reason, WORequestHandler aHandler,
String actionClassName, String actionName, Class actionClass,
WOAction actionInstance) {
if (actionInstance != null) {
if(actionInstance.context().hasSession())
actionInstance.context().session().terminate();
com.hb.pages.Home home = (com.hb.pages.Home) pageWithName
("Home", actionInstance.context());
return home.generateResponse();
} else {
return handleException(exception, null);
}
}
this traps the error and sends them back to the homepage, however,
it freezes the instance.
The first thing that I would do is to follow the advice that Gary
Teter just posted and get a thread dump after it deadlocks. That
should point to where the actual problem is.

Anyone have any obvious ideas why a bad directAction would freeze
an instance?
I noticed this from a bad link going to a non-existent DirectAction.
It might vary by version :-(, but in at least some versions, if
performAction throws and there is a session, the session will not
get checked in which deadlocks that session. If the app is not
dispatching requests concurrently, that will deadlock the entire app.
The solution to that one is to wrap performAction in a try..catch
block and pass the exception off to Application.handleException.
