DRAFT KB-XXXX Current user activity is blank even after clearing the search indices


When the current user activity record in the admin console is blank and the following error is seen in the application server log:

YYYY-MM-DD HH:MM:SS.MMM INFO [ajp-nio-8009-exec-2] org.apache.catalina.core.StandardWrapperValve.invoke YYYY-MM-DD HH:MM:SS,MMM [ajp-nio-8009-exec-2] WARN - Could not record user activity: secCtx=BPMSVC7, authDetails=AuthenticationDetails[ts=YYYY-MM-DD HH:MM:SS.MMM, entryPoint=PORTAL, clientIpAddress=XX.XX.XXX.XX, clientUserAgent=Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.92 Safari/537.36] -- java.lang.NullPointerException


This is due to the fact the user is using an Apache version earlier than 2.4 and the mod_jk connector earlier than 1.2.42.



  1. Update the mod_jk connector to 1.2.42 and Apache to 2.4
  2. Or add the following lines to the bottom of the httpd.conf file 
      SetEnvIf Server_Addr "(.*)" AJP_LOCAL_ADDR=$1

Then restart Apache.
