I have a big backup file more than 400M. I have tried the patch for version 1.8.3. It does not correct the problem. But I observe the high usage of server memory while restoring. I tried to set memory_limit = 512M(in php.ini) or raise_memory_limit(“512M”) (in backup/restore.php). Finally the problem has been solved.
