Event “1b”
SRTP Server
events

ББББББББББББББББББББББ

This event is logged by the Service Request Transfer Protocol (SRTP) Server mod-
ule when an exceptional condition occurs. Entry 1 will always be zero.
Entry 2

contains a code unique to each type of unexpected event. Entry 3 con-

tains a code identifying the SRTP Server software component which logged the
event.
Entries 4, 5, and 6

identify additional information specific to the type of event de-

scribed in entry 2.
Entry 2

codes are given below.

“LAN data memory exhausted-check parms; resuming”
Internal error: QCreate failed to create a queue header.

“LAN data memory exhausted-check parms; resuming”
Internal error: Failed to QAlloc a buffer. Entry 4 contains the buffer size in
bytes.

“LAN I/F can’t init-check parms; running soft Sw utl”
Internal error: Failed to PoolAlloc a buffer pool. This event causes the
Ethernet Interface to restart. If this error occurs within the first 60 seconds
after the Ethernet Interface was restarted or power cycled, the automatic
restart will force the Ethernet Interface into the Soft Switch Entry utility.

“LAN data memory exhausted-check parms; resuming”
Internal error: Failed to BuffAlloc a buffer. Entry 4 contains the buffer size in
bytes.

“LAN system-software fault; resuming”
Internal error: An endpoint identifier other than that of the parent has
appeared in a context in which a parent endpoint is expected. Entry 4 contains
the offending endpoint identifier.

“LAN system-software fault; resuming”
A TCP error event was issued to the SRTP Server. In many cases there may be
a log entry immediately preceding this one which has an event code of “0x12”;
this entry may indicate the reason for sending the TCP error event. Entry 4
contains the number of the local endpoint (0H-0fH) to which the error was
issued.

“LAN system-software fault; resuming”
Internal error: Failed to tcpmopen a parent endpoint as part of SRTP Server
task initialization. As a result, any incoming TCP connections to SRTP will be
rejected by TCP (via RST).

“LAN system-software fault; resuming”
Internal error: Failed to tcpaccept an incoming TCP connection.

“LAN system-software fault; resuming”
Internal error: Failed to tcpattach an endpoint identifier to an incoming TCP
connection.

“LAN system-software fault; resuming”
An attempt to tcpread from a TCP connection failed. Entry 4 contains the
number of bytes requested to read. Entries 5 and 6 are a segment:offset base
address of the memory to receive the read bytes.

“LAN system-software fault; resuming”
An attempt to tcpwr to a TCP connection failed. Entry 4 contains the number
of bytes requested to write. Entries 5 and 6 are a segment:offset base address
of the memory to supply the written bytes.

“LAN system-software fault; resuming”
Internal error: Detected a NULL mailbox pointer.
