Hi,I am using Moodle which itself uses SQL for the database. Problem is that, when I run the email plugin and execute the command, the refresh time of the page becomes high (in the order of 3-5 minutes) and at the end, I see this message Debug info: MySQL server has gone away SELECT id, sid, state, userid, lastip, timecreated, timemodified FROM mdl_sessions WHERE sid = ? [array ( 0 => 'jqfbgd5b0q6e2l81bb5gb87mn3', )] Error code: dmlreadexceptionStack trace: - line 479 of /lib/dml/moodle_database.php: dml_read_exception thrown - line 1175 of /lib/dml/mysqli_native_moodle_database.php: call to moodle_database->query_end() - line 1551 of /lib/dml/moodle_database.php: call to mysqli_native_moodle_database->get_records_sql() - line 1523 of /lib/dml/moodle_database.php: call to moodle_database->get_record_sql() - line 1502 of /lib/dml/moodle_database.php: call to moodle_database->get_record_select() - line 286 of /lib/classes/session/manager.php: call to moodle_database->get_record() - line 82 of /lib/classes/session/manager.php: call to core\session\manager::initialise_user_session() - line 785 of /lib/setup.php: call to core\session\manager::start() - line 27 of /config.php: call to require_once() - line 30 of /index.php: call to require_once()
Although it looks like a bug in Moodle, but the guys said it is a MySQL issue. I am confused about that. If you have any idea please let me know. What does this error say exactly? Regards, Mahmood
