session name : SNAX buffer overload
Cause. A temporary condition occurred in which SNAX/XF or SNAX/CDF had
insufficient buffer space for the current processing requirements.
Effect. Data is not lost.
SNAX/HLS treats this condition automatically. The rejected send request is retried,
and the rate at which data is sent to this LU is slowed down. When the overload
errors cease, the submission rate is increased. This adjustment is automatic inside the
SNAX/HLS process and is invisible to the application, except for the slowdown of
data.
Recovery. If this condition persists and you are using SNAX/XF as your Tandem SNA
access method, consider increasing the size of the buffers available to the SNAX/XF
line handlers (the XPAGES parameter). If you are using SNAX/CDF as your Tandem
SNA access method, consider increasing the value of the DATAPAGES configuration
parameter. If this option is unavailable, you might want to redistribute your network
to reduce the overloading of the line on which this LU resides.
session name : Unexpected pacing response received
Cause. SNAX/HLS received a pacing response that it was not expecting.
Effect. The pacing response is discarded.
Recovery. Informational message. No action necessary.
