We have a problem with many processes in sleep state in the database. In the PHP error logs I find many of the following entries:

[10-Feb-2021 16:14:21 Europe/Berlin] Default exception handler: Datensatz kann nicht in der Datenbanktabelle bigbluebuttonbn gefunden werden Debug: SELECT * FROM {bigbluebuttonbn} WHERE id = ?
[array (
0 => 1684,
)]
Error code: invalidrecord

• line 1646 of /lib/dml/moodle_database.php: dml_missing_record_exception thrown
• line 1622 of /lib/dml/moodle_database.php: call to moodle_database->get_record_select()
• line 2673 of /mod/bigbluebuttonbn/locallib.php: call to moodle_database->get_record()
• line 58 of /mod/bigbluebuttonbn/bbb_ajax.php: call to bigbluebuttonbn_view_instance_bigbluebuttonbn()

Is this a bug in the plugin BigBlueButtonBN?
