my guess is that it's a database error. if your host has limits set on the number of connections per unit time that you're allowed, you may be exceeding this limit when importing users.
it could also mean that there are duplicate user_ids in the database. i've not run across this error in my integration (and I thought I had hit them all
). you may want to turn on debugging in G2 to see if it prints out any more details.
this is the offending chunk of code, i think:
PHP: › <?php $markers = GalleryUtilities::makeMarkers(sizeof($columns));
$query = 'INSERT INTO ' . $tableName . ' (';
$query .= join(', ', $columns);
$query .= ') VALUES (' . $markers . ')';
$this->_traceStart();
$recordSet = $this->_db->Execute($query, $data);
$this->_traceStop();
if ($recordSet === false) {
return GalleryStatus::error(ERROR_STORAGE_FAILURE, __FILE__, __LINE__);
} ?>
