    <p>I have this Perl/CGI to upload files and get the uploaded file size while uploaded.</p> <p>The script works fine for files under 500MB but the buffer (OUTFILE) stops writing the file after around 500MB. Here's the partial code:</p> <pre><code>$u_size = $ENV{'CONTENT_LENGTH'}; if ($u_size &gt; $max_size) {send_error ("Upload too big. Maximum size is $max_size bytes and your file is $u_size bytes.");} print_progress(0); # Set up uploading function $query = CGI-&gt;new(\&amp;hook); #define functions sub hook { if ($error) {return;} if (time &gt;= $next_print) { $next_print = time + $delay; my ($filename, $buffer, $bytes_read, $data) = @_; if ($check_mime) { $filename =~ m/\.([^\.]+)$/; $ext = lc($1); print $ext; $check_mime = 0; } $percent = $bytes_read / $u_size; $filename =~ m/\\([^\\]+)$/; $filename = $1; print_progress($percent, $u_size, $bytes_read, $filename); } } sub print_progress { open(PROG, '&gt;'.$uploaded_file_progress); print PROG '{"percent" : ' . ($_[0] * 100) . ', "total" : ' . $_[1] . ', "uploaded" : ' . $_[2] . ', "filename" : "' . $_[3] . '"}'; close PROG; } ############# $uphandle = $query-&gt;upload($query-&gt;param()); binmode $uphandle; if (!$error) { open OUTFILE, "&gt;" . $uploaded_file; binmode OUTFILE; while($bytesread = read $uphandle, $buffer, 1024) { print OUTFILE $buffer; } #while (&lt;$uphandle&gt;) {print OUTFILE $_;} close OUTFILE; } </code></pre> <p>If the script is not a problem, what other stuff that I have to check? Thanks.</p> <p>Edit: I have this in the log: Timeout waiting for output from CGI script. How do I get rid of this? I couldn't find a definitive answer on Google.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
