Bugzilla import fails in last step with a black screen

[Jira2 COST2]

Hello,

I am evaluating JIRA Software Server installation on a Ubuntu server (16.04 LTS) with MySQL server (5.6) using latest JDBC MySQL Connector (5.1.39) and I am trying to import Bugzilla tickets from our current server without any success. I manage to successfully connect to the MySQL database of Bugzilla using the wizard and after following all the steps and mapping all the necessary fields, I reach the last step to begin the import but it fails with a blank screen. There is no import done at the end. Our server has 8 GB of RAM and enough disk space available.

There is also a similar question but there is no reply. https://answers.atlassian.com/questions/38832151

Can anyone help or let me know what log file should I need to check in order to troubleshoot this issue?

Thank you very much!

Problem solved after upgrading to the latest version of JIRA 7.1.8 (at this time of writing). It looks like there was a bug to the previous version that was reported here https://jira.atlassian.com/browse/JRA-61179
