To work around this issue, use the steps below to disable RECYCLE_FACADES.

1. Log in to the vCenter Server with SSH
    
2. Create a backup of the catalina.properties file.
    

   cp /usr/lib/vmware-vsphere-ui/server/conf/catalina.properties /root/catalina.properties.bak

   
    
3. Run the following command to add a line to the end of the original catalina.properties file to disable RECYCLE_FACADES.
    

   echo "org.apache.catalina.connector.RECYCLE_FACADES=false" >> /usr/lib/vmware-vsphere-ui/server/conf/catalina.properties

   
    
4. Restart the vsphere-ui service with the below command.
    

   service-control --restart vsphere-ui
