Did you pass in an EO to the long response page from the session? If
so that's likely the cause.

I don't use the EC from the session, I use a new EC in the thread.
But I need to import a lot of records so I need to clean from to to
time, or I risk an out of memory:
if(rowcount%1000==0)
{
System.out.println(rowcount);
ec.saveChanges();
ec.rootObjectStore().invalidateAllObjects();
}

You are implementing it wrong. I am guessing that you are using an
EC from the session in the long response page. The thread needs
its own EC that it locks and unlocks.

HI,
I am writing an application to update Frontbase from FileMaker.
I use AjaxLongResponse in my interface to see the progress in the
browser.
But I always get an error:
<er.ajax.AjaxRequestHandler>: Exception occurred while handling

Is there a way to avoid this? Or am I impplementing this wrong?
I can see also next error):
Another Exception occurred while trying to clean the application:
