zx25d 426 Link <#>: Application timeout for inb. call on ZLU <#>!
Explanation: An Incoming CALL packet arrived on a ZLU that was
configured for Application inbound call
acknowledgment required. However, the application
did not accept or clear the call within the allowed
amount of time (40-50 seconds). A CLEAR Request
packet has automatically been transmitted. Note that
this message may appear in rare cases where the CPU
is put under extreme loads. If this is a frequent
problem and the application has been correctly coded,
you may need to upgrade to a higher performance
processor.
Action: Correct the application program or modify the
configuration to allow the X.25 protocol driver to
automatically accept inbound calls.
zx25d 427 Link <#>: Reset request timed out on VC ZLU <#>!
Explanation: An outbound Reset Request packet was transmitted,
however the remote DXE did not respond with a Reset
Confirmation packet within the time allowed (Timer
T12 or T22). The Reset Request will be retransmitted
unless R22 has been exceeded.
Action: Check the remote DXE and correct any problems
found.
zx25d 428 Link <#>: Application timeout for inb. reset on ZLU <#>!
Explanation: An Incoming RESET packet arrived on a ZLU that was
configured for Application Reset Confirmation
required. However, the application did not confirm the
reset (using zx25reset_conf) within the allowed amount
of time (40-50 seconds). A Reset Confirmation packet
has automatically been transmitted. Note that this
message may appear in rare cases where the CPU is
put under extreme loads. If this is a frequent problem
and the application has been correctly coded, you may
need to upgrade to a higher performance processor or
your application may need to run at a real-time
priority.
