I am trying to upgrade our Moodle version 2.8.8+ to Moodle 3.1.13 from our test server, and I am getting an internal error server (500), about ten minutes into the upgrading process. We are using MySql version 5.6.11 and php version 5.6.31 and Apache version 2.4. I have attached 2 screen shoots of the moodle environment of 2.8.8+ version prior to the upgrade. One of the screen shoots (second one) it shows a warning about unsupported_db_table_row_format. It says that the database has table using Antelope as the file format, and it is recommended to convert the tables to the Barracuda file format. Ignored the warning and went ahead with the upgrade. Is this what is causing the above mentioned error, or is the process timing out. Because the Apache error log is showing a mod_fcgid: process 2016 graceful kill fail, sending SIGKILL.
