Fix Java Stack Error
CIP Reporting 'How to' Guide
This guide will show you to fix Java Stack Error.
The symptom is found by checking the application-error.log and seeing Java socket failures because tomcat isn't running.
Solution:
1.- Edit the following file in a text editor/svc/tomcat/conf/server.xml.dist
and set SSLEngine=off
.
2.- Stop Services by going into the CIP Shell and running the command service stop
, wait for all processes to stop, this can be checked by running the command ps
, the only process left should be the CIP Shell process.
3.- Reconfigure Services by running the command service configure
so the changes we made to the file take place.
4.- Restart Services by running the command service start
.
Done!
A software upgrade fixes this too but for a system that’s down it’s best to just hot fix it by following the instructions above.
