SOCKET

SOCKET

SOCKET/4/ASYNACCEPTFAIL

Message

SOCKET/4/ASYNACCEPTFAIL:Failed to allocate the file describer for the sub socket when accept was called to accept incoming connection request. (Time=[ULONG], TaskName=[STRING], TaskId=[ULONG], SocketId=[ULONG], ErrorCode=[LONG])

Description

Failed to allocate the file descriptor to the socket when the Accept function was called to receive the connection request.

Parameters

Parameter Name Parameter Meaning
Time indicates the time when the log is generated.
TaskName indicates the task name.
TaskId indicates the task ID.
SocketId indicates the socket ID.
ErrorCode indicates the error codes, that is, -101, -24, and -55.

Possible Causes

1. Because the system memory was insufficient, namely, the memory was used up or nearly used up, the TCP listening socket could not receive the connection request from the client, and the connection failed.

2. The number of socket connections of the current task exceeds the upper limit (23 x 1024). Therefore, the file descriptor cannot be allocated to the socket, and the connection fails to be set up.

Procedure

  1. If the fault is caused by the insufficient memory, cancel some memory-consuming and unnecessary applications.
  2. If the fault is caused by the insufficient file descriptors, cancel some applications that occupy a large number of file descriptors. In this manner, you can release enough file descriptors for current applications.

SOCKET/1/BINDPEERIP

Message

SOCKET/1/BINDPEERIP:Failed to bind the peer IP because a socket with same state already existed.

Description

Failed to bind the peer IP address because a socket in the system had the same status as that of the current socket.

Parameters

Parameter Name Parameter Meaning
None None

Possible Causes

1. The peer IP address was repeatedly set.

2. The system had a socket with the same local IP address, local port number, remote IP address, remote port number, and VPN index as that of the socket to be set.

Procedure

  1. The log is generated when the system faces an unknown fault. The fault causes the relevant routing protocol unavailable. Then you need disable the routing protocol and then enable it.

SOCKET/4/CANTGETLSTNSOCK

Message

SOCKET/4/CANTGETLSTNSOCK:Failed to obtain the ID of the listening socket. (TaskId=[ULONG], SocketId=[ULONG], ErrorCode=[LONG])

Description

Failed to acquire the listening socket ID.

Parameters

Parameter Name Parameter Meaning
TaskId indicates the task ID.
SocketId indicates the socket ID.
ErrorCode indicates the error codes, that is, -22 and -107.

Possible Causes

A software error occurred in the system. Then the relevant task control block could not be found according to the task ID, or the relevant socket could not be found according to the file descriptor. You can consider that the fault has nearly no chance to occur.

Procedure

  1. Collect log information and configuration information, and then contact technical support personnel.

SOCKET/4/EXCEEDMAXQLEN

Message

SOCKET/4/EXCEEDMAXQLEN:The number of messages in the asynchronous message queue was greater than the message upper limit. (Time=[ULONG], TaskName=[STRING], TaskId=[ULONG], SocketId=[ULONG], ErrorCode=[LONG])

Description

The number of messages in the asynchronous message queue exceeded the defined upper limit.

Parameters

Parameter Name Parameter Meaning
Time indicates the time when the log is generated.
TaskName indicates the task name.
TaskId indicates the task ID.
SocketId indicates the socket ID.
ErrorCode indicates the error code, that is, -8.

Possible Causes

Each asynchronous socket has a queue to receive messages. This log indicates that the message queue was full and no new message could be received. The cause is that the speed in which the CPU read messages was slower than the speed to generate messages. In most cases, the fault is caused when a large number of packets are generated in the network, and the CPU is too busy to handle received messages in time. Therefore, the message queue becomes full and the received subsequent data is discarded.

Procedure

  1. Reduce the workload of the CPU by canceling some processes that are CPU-time consuming and unnecessary.
  2. If possible, wait till the CPU is idle and then configure relevant tasks.
  3. Collect log information and configuration information, and then contact technical support personnel.
