Yellowfin issues - disconnection troubles
I am a part of the Sample6 team and we faced a few problems on our yellowfin(YF) server.
We use AWS EC2(m4.large) and docker as a wrapper for YF.
1. After some time(about ~24 hours or less, It was about 5-6 times), We cannot login into YF.
Login page works but after the login operation - a white screen is appeared and we are not able to check reports.
I've attached some logs from our server and the log file has a lot of different exceptions.
We have to restart tomcat which is not a good solution for us.
Now, it has been working for four days without any issues, however we would to know what might be ajusted to be able to avoid the problem in the future.
2. Chrome browser had some errors in the browser console and endless title 'Creating reports.. please wait' is appeared.
It was after restart YF server twice.
A few screenshots with errors were attached.
3. We also have some performance issues. For the issue we have increased -xmx parameter from 1024mb to 4096mb. What else we can adjust just to be able to use YF without performance issues?
Thanks in advance
