APAR status

  • Closed as program error.

Error description

  • When the connection between SSP and the outbound PS is lost and
restored, the CD proxy adapter can think that its listener is
down, while the local inbound PS is still accepting connections
on its behalf and queueing them up.  The SSP CD adapter ignores
the connections. If the situation goes undetected, the load
balancer health check pings can lead to build up of
DataConduitApiImpl connection objects and eventually cause the
OutOfMemory  exception.

Local fix

  • Stop the SSP CD adapter to clear the DataConduitApiImpl
objects, and restart it to re-establish a functioning listener
with the local inbound PS.
