Identifying and Resolving MC-271325 Log Floods

Recognizing the MC-271325 Bug

Server administrators reviewing log files often encounter extensive walls of text caused by the MC-271325 bug. Whenever a client disconnects, an unhandled condition can cause the server to output full exception stack traces referencing the clientbound/minecraft:disconnect packet.

Common signs of this issue include:

• Large server log files filled with repeated network exception messages.
• Terminal scrollback moving too quickly to read during busy connection periods.
• Console output repeating disconnect packet errors every time a player leaves, logs off, or loses connection.

Clearing the Error Output

The mod acts automatically to resolve the bug and eliminate stack trace spam from your logs.

1. Open your server log directory and inspect your latest log files after active player sessions.

2. Search the log text for entries referencing clientbound/minecraft:disconnect.

3. Verify that the previous stack trace errors no longer appear when players drop connection, log out, or get kicked.

4. Confirm that normal server disconnect notices continue functioning as expected without the extra error text.

By suppressing these invalid exception traces, your logs become much easier to parse for legitimate server issues and player activity.
