Thank you for the reply Michael. I have just published the issue.
I was using as usual -Xmx4g. Now I've just tried with 6GB and open and
close a single transaction for every query like that on the different
indexes and I do not get this exception.
So now it has more need of memory for the same operation. I try on other
cases. Tell me if there are news on the issue please.
Thank you.
Regards
Rita
