iphone x backlog

TCP establishes the connection is to carry on three handshake, but whether completes three times handshake, the server handles (accept)?The backlog is actually a connection queue, before Linux kernel 2.2, the backlog size includes the semi-connected state and the full-connection state of the two queue sizes.Semi-connected state: When the server is in the listen state when the client SYN message is received,

Int listen (int fd, int backlog ); the socket system calls listen only for use by the TCP server. It does two things: 1. converts unlinked interfaces to passive interfaces, indicating that the kernel accepts connection requests to this interface. After the system call is called, the TCP state machine has closed to listen. 2. the second parameter sets the maximum number of connections that the kernel queues for this set of interfaces. for the seco

Symptom description:Email server A and email server B are set at the front-end. After the front-end receives the email, it is delivered to the mailbox in the backend server. After receiving the external email, the front-end cannot deliver the email to the backend mailbox, this results in a backlog of emails on the front-end server. It takes about 25 minutes for internal mail delivery to arrive.By looking at the various services on the front and back e
