textarea content is randomly cut

Hello, All! > cat test.php <form action=test.php method=post> <textarea name=a cols=40 rows=18><? echo $a ?></textarea> <textarea name=b cols=40 rows=18><? echo $b ?></textarea> <input type=submit> </form> > I experience great problems with this simple code. Just enter several KB into each field and repeatedly press submit. After random number of pushes (~5) the second field appears to be cut, and it ends with the '%'. The text pattern is "asdfasdfsdf\n", no unusual characters. When the text is 'real', it's sometimes sufficient to add one space in the middle to see the above effect. Win9x + IE or Netscape -> FreeBSD 3.4 + PHP 4.0 + Apache 1.3.12 Could somebody be so kind to comment this? Thanks for your attention. P.S.
