原因

As the Jira application starts up, it goes through the following steps when starting the Plugin System:

1. $JIRA_INSTALL/atlassian-jira/WEB-INF/classes/atlassian-bundled-plugins.zip が $JIRA_HOME/plugins/.bundled-plugins に展開されます。
2. $JIRA_HOME/plugins/installed-plugins が $JIRA_HOME/plugins/.osgi-plugins に展開されます。

This is a fairly resource intensive process and can place a sizeable load on the I/O of the disk and CPU of the machine that is hosting the Jira application instance. If the required resources aren't available, the plugins may timeout and cause the application to be left in an unusable state.

回避策

It is possible to increase the plugin timeout period by adding the -Datlassian.plugins.enable.wait=300 argument to the Jira application startup arguments, as in Setting Properties and Options on Startup.

ソリューション

1. Ensure the machine meets minimum requirements and has enough memory, CPU, and disk I/O available as outlined in Jira applications requirements.
2. Test your disk speed, as per our Testing Disk Access Speed KB. A slow disk or network mount can indicate problems with a Jira application startup as it will not be able to write to the disk in time.
3. Check if any Antivirus is running on the host. Jira application and Antivirus are known to be mortal enemies - even if an exception is set in the Jira application directory, it may not be respected. Try disabling the Antivirus altogether and starting Jira application up.
