Read ErrorScenario: Mary couldn't make out what Joe was saying anymore, so she hung up rather than lose his messages (data). A read error occurs when a server cannot successfully read from a user's client. Servers gather information from the client by text, setup, and other items.When the server receives an error when reading from a client, it then disconnects the user, resulting in a read error quit message.
Write Error Scenario: Mary was trying to talk to Joe but didn't think she was getting through, so she hung rather than lose his messages (data). A write error occurs when a server cannot successfully write to a user's client. When the server receives information, it usually responds with information of its own. When the server receives an error when writing to a client, it then disconnects the user, resulting in a write error quit message similar to the read error format.
Ping Timeout Error Scenario: Mary, having been raised in a household with too many kids and always craving attention, keeps asking to make sure that Joe is still on the line and listening. If he doesn't reply fast enough to suit her, she hangs up. Servers automatically ping users at a preset time. The reason for this is to ensure the client is still connected to the server. When you see "PING? PONG!" results in your status window, it means the server has pinged your client, and it has responded back with a pong to ensure the server that you are still connected. When this does not happen and you disconnect without the server's knowledge, the server will automatically disconnect the user when it does not receive a response, resulting in a ping timeout. Ping timeouts occur to EVERYONE.
Broken pipe Error Scenario: Mary had picked up a sticky note with a message she needed to relay to Joe, but somehow between her hand and her mouth, the message got misplaced. Mary was trying to talk to Joe but didn't think she was getting through, so she hung up rather than lose his messages (data). A broken pipe error occurs when the server knows it has a message but can't seem to use its internal data link to get the data out to the socket.
Miscellaneous Scenario: Lots of other reasons; perhaps the operator broke in and gave Mary a message that made her doubt the validity of the call so she hung up.
