MySql Error: ERROR 2006 (HY000) at line 1041: MySQL server has gone away


ERROR 2006 (HY000) at line 1041: MySQL server has gone away


Location in Xampp Server


The error message “MySQL server has gone away” usually occurs when the client cannot connect to the MySQL server. This can happen for a variety of reasons, including but not limited to:

  1. Timeouts: The server closed the connection due to inactivity. This happens if the client was idle for more than wait_timeout seconds or if a network problem caused a disconnect.
  2. Packet Too Large: The client tried to send a packet bigger than max_allowed_packet. Increasing the max_allowed_packet size on the server or breaking down the data into smaller chunks from the client side can resolve this.
  3. Server Restarted: The MySQL server was restarted, which also closes all connections.
  4. Out of Memory: The server could not allocate memory for the connection or was killed by the system (OOM Killer) due to out of memory.
  5. Wrong Connection Parameters: The connection parameters (host, username, password) are incorrect.
  6. Network Issues: There could be network connectivity issues between the client and the server.

To resolve this error, consider the following actions based on the possible causes:

  • Increase Timeouts: Increase the wait_timeout and interactive_timeout on the MySQL server if connections are dropping due to inactivity.
  • Increase Max Allowed Packet: Increase the max_allowed_packet size in the MySQL server configuration. This is particularly important if you’re dealing with large blobs or long queries.
  • Check Server Status: Ensure that the MySQL server is running and that there are no recent restarts or crashes.
  • Optimize Queries and Data: If you’re sending large amounts of data, consider breaking it down into smaller chunks.
  • Check for Network Issues: Verify that there are no networking issues between the client and server. Tools like ping and traceroute can help diagnose such problems.
  • Server Configuration and Logs: Check the MySQL server’s error log for any messages related to connections being killed or other errors that might indicate why the server is unavailable.
