Hello Jeanfrancois and Jagadish;
Thank you very much for your interest.
I guess connection pool related lines was exceptional. It's appears in only one of dump files.

While i'm investigating i've found that it may be an Toplink related issue according to:

DataBaen.getItem method in stack traces running a query like this:
        Item item = (Item) em.createQuery(
                "SELECT distinct i from Item i left join fetch i.images left join fetch i.itemSpecs where i.itemId = :itemId").setParameter("itemId", itemId).getSingleResult();

Maybe it is about fetch join related. I've changed query as:
 SELECT i from Item i where i.itemId = :itemId

Now i'm observing if that will happen again.


Regards.
