13 “LAN system-software fault: aborted assoc. & resuming”

Internal error: An attempt to allocate a work block failed. Entry 3 contains
the aborted channel number.

14 “LAN system-software fault; resuming”

Internal error: Additional unsolicited mail or service response data arrived
from the Backplane (PLC) Driver when such data was unexpected.

15 “LAN system-software fault; resuming”

Internal error: A mailbox buffer pointer was found to be NULL.

17 “LAN system-software fault: aborted assoc. & resuming”

The Backplane (PLC) Driver returned bad status in response to a request.
Entry 3

may contain the aborted channel number or 0 if no channel was

aborted. Entry 4 contains a status code indicating the type of failure. Valid
values for these codes are listed under the description of SRTP Server (event
1b) Entry 2 codes e-13. Entry 5 uniquely identifies the request that failed.
This problem may occur due to the Ethernet Interface being asked to
perform beyond its capacity. Try transferring less data per message or
establishing fewer simultaneous connections.

18 “LAN system-software fault: aborted assoc. & resuming”

Mailbox traffic of unwanted type arrived from the Backplane (PLC) Driver.
Entry 3

may contain the aborted channel number or “C00” if no channel was

aborted. Entry 4 identifies the offending traffic type.

19 “LAN system-software fault: aborted assoc. & resuming”

Internal error: The Channel API received a backplane transfer response of an
unwanted transfer class. Entry 3 contains the aborted channel number.
Entry 4

contains a code identifying the class. Valid class codes are:

0 UNKNOWN

1 READ_DATA

2 WRITE_DATA

3 WRITE_DCS

4 WRITE_CRSW

5 WRITE_CSB

1a “LAN system-software fault; resuming”

Internal error: A Backplane (PLC) Driver event indication routine was
invoked, but the Channel API does not have any use for such an event.
Entry 4

contains a Backplane (PLC) Driver task identification. Entry 5

contains a request identification number.

1c “LAN system-software fault: aborted assoc. & resuming”

Internal error: A NULL buffer pointer was detected. Entry 3 can contain the
aborted channel number.

1d “Backplane communications with PLC fault; lost request”

Internal error: A request to notify the Channel API of the next CPU scan
failed.

1e “LAN system-software fault: aborted assoc. & resuming”

Internal error: An attempt to allocate a new channel machine failed. Entry 3
contains the requested channel number.

1f “Bad local application request; discarded request”

A COMMREQ arrived to the Channel API containing a command code that
was not recognized as a Channel API command. Entry 3 contains the
command code.
