tengine Kernel parameters
tcp_max_syn_backlog: 16384
Maximum port backlog Kernel restrictions . This parameter limits Server application The maximum number of ports that can be set backlog value ( Corresponding to port syn_backlog and backlog The queue length ). The motivation is to limit... On servers with limited memory / Avoid application configuration backlog Value to run out of kernel memory . If the application settings backlog Greater than this value , The operating system will automatically limit it to this value .(tengine listen backlog : 2048)
tcp_abort_on_overflow: 0
When tcp Connected 3 After Lu shook hands , Put the connection in ESTABLISHED State and deliver to the application backlog When queuing , Will check the backlog Is the queue full . If it's full , The usual behavior is to restore the connection to SYN_ACK state , In order to create 3 The last way to shake hands ACK The false appearance of accidental loss of a bag —— In this way, it can be retransmitted after the client has timed out ACK —— To try to enter again ESTABLISHED state —— As a repair / Retry mechanism . If enabled tcp_abort_on_overflow It's checking that backlog When the queue is full , Direct hair RST Package to the client to terminate the connection —— At this point, the client program will receive 104 Connection reset by peer error .
