MySQL Error 1158: Communication Packet Read Error
Description
This error indicates that MySQL encountered an issue while attempting to read data from the network connection. It typically occurs when there's a disruption in data transfer between the client and the MySQL server, often due to network instability, timeouts, or connection drops.
Error Message
Got an error reading communication packets
Known Causes
4 known causesUnstable Network Connection
Intermittent network outages, firewall blocks, or routing issues can disrupt the data stream, leading to incomplete packet reads.
Server-Side Read Timeout
The MySQL server's `net_read_timeout` setting might be too low, causing the server to close the connection if no data is received within the configured time.
Client-Side Timeout
The client application or library might have a shorter timeout configured, causing it to prematurely abandon reading data from the server.
Exceeded Max Allowed Packet Size
If the data packet being sent or received exceeds the `max_allowed_packet` limit on either the client or server, the communication can fail.
