Progress database gets halted by some queries

Hi,

Using the following database/driver:

Database Version = 11.7.4
Driver Name = OpenEdge
Driver Version = 5.1.4.000130 (F000322.U000140)

We are able to succesfully make queries to the database via a java component, however, when performing longer queries problems occur. The queries no longer return anything and the connection seems stuck.

Here is the spy log following a single thread:

Has anyone had this kind of problem? I wonder if it is because of too many queries..?

Thanks,
