Our apache server crashed several times. We found out that before
each crash, the error_log file grows up to 2 GBytes, containing the HTML code from  one page of a particular site (always the same page).

We checked this page and found that it was using ob_start() function.
After the desactivation of this function in php.ini, the server does not crash
any more.

We think there is perhaps a potential security hole in this function because
if datas can be writen into error_log , they might be written anywhere else.

Let us know about it

Regards,

S?bastien BLON

This should be fixed in PHP 4.0.5. But please try the
soon to be released 4.0.6 release candidate 3:
