Error description
This fixes an intermittent problem with the DRS (Data
Replication Service) component with 'get' operations. An
internal object with communication resources was not being
properly synchronized. As a result, it could be incorrectly
shared by multiple threads, and messages would not be properly
received. This problem could be experienced by all WebSphere
Application Server components which use the services of DRS.
