The secondary One-Click server failed to load and after attempting to restart both webtomcat and tomcat, as well as a server reboot, we are now seeing the following:
Type Exception Report
Message Request header is too large
Description The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

Release : 21.2
Component :
The maxHttpHeaderSize needed to be increased in the server.xml file.
The solution is to increase the http header size in OneClick by doing the following on the OneClick server: Create a backup of the $SPECROOT/tomcat/conf/server.xml file Edit the $SPECROOT/tomcat/conf/server.xml file Find the maxHttpHeaderSize="8192" parameter Change to maxHttpHeaderSize="16384" Save the change Restart Spectrum tomcat
