DC/LDM Logging Location Codes
DC/LDM (Data Comm Logical Device Manager) is a module between
NS Transport and the LAP-B Driver, which helps provide NS over
point-to-point Router networks.
2 CLAS0000 MESSAGE: Send_msg error
CAUSE: While DC/LDM was attempting to send a message to another
module, for some normal purpose (other than an error reply), the
system routine send_msg reported an error.
ACTION: No message was sent. DC/LDM is now “sick” and cannot
continue operating. An asynchronous error message was sent to all
modules to which DC/LDM was bound. See Appendix A , “Submitting a
CR,” of this manual.
4 CLAS0000 MESSAGE: A connect event has been received from the lower
manager
CAUSE: This is not an error. DC/LDM received a connect-completion
event message from one of the lower level drivers bound to it. This logs
the fact the link is now connected.
ACTION: No action required. An asynchronous event message was sent
to all modules to which DC/LDM was bound.
12 CLAS0000 MESSAGE: Unable to obtain a message frame from target pool
CAUSE: While DC/LDM was attempting to get a message frame from
another port, for use as an event or reply message, the system routine
get_ msg_frame reported an error.
ACTION: DC/LDM is now “sick” and cannot continue operating. No
message frame was obtained. See Appendix A , “Submitting a CR,” of
this manual.
15 CLAS0000 MESSAGE: Write request is invalid in current state
CAUSE: A write event was invalid, or DC/LDM is sick, and a
Compatibility mode write request was being worked on. Since that
write cannot be completed, DC/LDM notifies the CM sender, and logs
the original error.
ACTION: See Appendix A , “Submitting a CR,” of this manual.
16 CLAS0000 MESSAGE: Send_msg error while issuing CM reply
CAUSE: During error processing of an invalid write event, DC/LDM
encountered another error while trying to send the Compatibility mode
error reply message back to the requester, when the system routine
send_msg reported an error.
