Description:
Closed Issues in 5.2.1 Hotfix 8 (This Release)

CR: BC-6158

Under high load conditions with large number of request response operations,
intermittent failures to close the database statements properly may
occur and consumes all system resources over time that could eventually
result into an abnormal shutdown on the process engines. This problem has
been fixed.

Earlier before the fix, the database resultset was fetched as a stream,
but due to intermittent failures, the fetch is read fully and closed. To
maintain backward compatibility, a new system property is added with a value
of false not to read fully. The property needs to be added in each of the
deployed engine .tra file and the property to be added is

  java.property.bc.hibernate.useJDBCBinaryStream=false|true

A value of 'true' would let the database resultset to be read fully before
closing the resultset rather than using the Database's stream mechanism.
