I don't see these directories/files in my prestashop folder OS: Debian, on a VPS

Hello, I am working on a school project, and currently I am stress testing the application. When the server is stressed (100 threads from jMeter), I get this warning: Warning: sprintf(): Too few arguments in /db/DbPDO.php on line 102 Any idea what could be wrong? Is the server too low specs? PS: the 102 line is: $this->link = $this->_getPDO($this->server, $this->user, $this->password, $this->database, 5);
