Local fix
Problem summary
The CoreDaemon kept adding bytes to a StringBuffer after the connection was lost. This was generating an OutOfMemoryError.
Problem conclusion
An extra check was coded into the CoreDaemon to prevent adding bytes to a StringBuffer when connection is lost. The problem listed in this APAR has been resolved with IBM Rational Developer for System z V7.6.2.1 Fix Pack which is available from the Recommended Fixes support download page: http://www-1.ibm.com/support/docview.wss?rs=2294&uid=swg27006335
