What it looks like in the log

Any one of these lines is enough. The agent matches them locally, on your server.

logs/latest.log
  • [ERROR] while disabling

Symptoms

  • When the server stops/restarts, the log shows an error while disabling a plugin
  • After a restart, the plugin's most recent data changes may be lost (not saved on shutdown)

Cause

The plugin's onDisable method threw an exception. The plugin may not have saved its data (database, files) or closed its resources.

Possible causes

  • A plugin bug when saving data on shutdown
  • A resource is already unavailable at shutdown: the database is closed, a dependent plugin was disabled earlier, the jar was replaced while running
  • Disabling via /reload or PlugMan, which the plugin does not support

How to fixLow risk

  1. Use the evidence to identify the plugin and the exception (the next line and Caused by:).
  2. After startup, check that this plugin's data is intact (recent changes, files in plugins/<plugin>/, database tables).
  3. Do not replace a plugin's jar while the server is running and do not use /reload/PlugMan — stop the server completely.
  4. Update the plugin; if the error recurs on a normal shutdown, report it to the author with the full trace.
