#define ERROR_ST_CONNECT                    1018

This error means "cannot connect to the server.

Please specify the version, environment, and reproduction method.

TRANS_BY_GPT3

[gqf2008]

Version: 2.0.195
Environment: CentOS 6.2 64 bit

Reproduction method:

1. One publishing server is responsible for publishing only and only allows two edge servers to pull streams. The publishing server only hooks the connect publish close callbacks.
2. When there is a playback request, the two edge servers pull the stream from the publishing server. The edge servers only hook the connect play close callbacks.
3. At first, it was thought that there was a problem with the implementation of the hooked API, so the hooks were completely disabled. However, through log observation, the same problem was found when connecting to port 1935 of the publishing server.
4. The two edge servers have F5 in front (triangle transmission) and do port detection/S on port 1935.
5. The number of concurrent connections on the edge servers does not exceed 100.
6. This problem can be reproduced by continuously clicking play and stop in the VLC player, and VLC reports an error of being unable to connect to the backend.

By querying relevant technical documents, it is said that after setting the socket to non-blocking, calling the recv function before the data packet is sent will result in this error. The program needs to ignore this error and continue looping to read. I hope this information is helpful in fixing this issue. Thank you.

TRANS_BY_GPT3

[winlinvip]

Well, let me see. It seems to be saying that it cannot connect to your http callback server. It shouldn't be a problem with recv yet.

TRANS_BY_GPT3

[gqf2008]

After closing the hook, it is still the same, connecting to the publishing server also reports 1018 (No such file or directory).

TRANS_BY_GPT3

[winlinvip]

Is the release server SRS?

TRANS_BY_GPT3

[gqf2008]

Yes.

TRANS_BY_GPT3

[gqf2008]

When there is a 1018 (No such file or directory) error on a connection of the edge server, the client can still connect to the edge SRS and play, but there will be frame drops and freezing.

Addendum, I am using version 2.0.197 and have set the srs as the Edge node.
mode remote;
The sourced stream can always be played normally. However, when accessing the SRS edge node, there is a more than 50% chance of error if the player disconnects and reconnects immediately. If the disconnection lasts for more than 10 seconds, there will be no error.

Upon investigating the code, the error message occurs in
SrsEdgeIngester::connect_server -> srs_socket_connect -> st_connect -> st_netfd_poll -> st_poll, and the returned errno is ENOENT (No such file or directory). Packet sniffing shows that communication is normal.

The problem seems to arise when the sourced connection is closed within a few seconds of no one watching after the last client disconnects. If there is a new stream playing for the first time during this period, it is prone to failure in the sourced connection. This issue persists in a loop and is also affected by different vhosts. This problem does not occur in version 1.0.
