Symptoms
When importing a large number of users or groups into a directory in Crowd, the import fails after a long time with a system error.
The following appears on screen and also in the atlassian-crowd.log:
1
2012-03-21 06:37:49,576 http-8095-4 INFO [atlassian.xwork.interceptors.TransactionalInvocation] Invoking rollback for transaction on action '/console/secure/dataimport/directoryconfirmation.action (DirectoryConfirmation.execute())' due to throwable: java.lang.IllegalStateException: getAttribute: Session already invalidatedCause
The amount of time it took to perform the directory import exceeded Tomcat's session-timeout value (which is set to 30 minutes by default). This issue is tracked here: CWD-2638 - Import failed despite being reported is finished due to 'Session already invalidated'.
Workaround
Make a note of how long it takes before the import fails.
Locate and open <crowd_install>/apache-tomcat/conf/web.xml in a text editor.
Locate the following line and increase the numeric value (in minutes) as necessary to accomodate the import (currently set to 30 in this example):
1<session-timeout>30</session-timeout>ℹ️ For more details on the Tomcat web.xml, please see: http://tomcat.apache.org/tomcat-6.0-doc/appdev/web.xml.txt
