Installation Error: What is line58 error?

I get this error message:

<strong style="color: A00000">An error occured on line 58 in file /home/lcvirtualdomain/tokyoboarderz.org/htdocs/forum/upload/include/dblayer/mysql.php.</strong><br /><br /><strong>PunBB reported:</strong> Unable to connect to MySQL server. MySQL reported: Lost connection to MySQL server during query<br /><br />

My sql server is working fine and I am able to access with no problem, but somehow I get this "lost connection to MySQL server" error during installation...I re-uploaded the specified file but in vain. Please help><! Thank you!
