APAR Error Description / Circumvention
-----------------------------------------------
An ACK was not sent for incoming data when there is outgoing
data that has not been ACKed at the time of the incoming data
packet.
CORRECTION FOR APAR MA41966 :
-----------------------------
The code was updated to ACK incoming data appropriately.
CIRCUMVENTION FOR APAR MA41966 :
--------------------------------
None.
DESCRIPTION OF PROBLEM FIXED FOR APAR MA41795 :
-----------------------------------------------
ioctl(SIOCSENDQ) is returning 0 for the number of bytes unACK'ed
instead of returning an error when the connection is closed
before sent data is ACK'ed.
CORRECTION FOR APAR MA41795 :
-----------------------------
An error will be returned on ioctl if the connection is closed
before all sent data has been ACK'ed.
CIRCUMVENTION FOR APAR MA41795 :
--------------------------------
None.
Activation Instructions
None.
Special Instructions
