Hi all I'm upgrading PHP version from PHP 4 to 5.3.0 and Apache to 2.2.13, but I'm facing a weird problem on the following statement: $StringaParametri=exec('java -cp ..\\java rsa6230 ' . $Token); It works on PHP 4 and PHP 5 CGI, but it hang Apache using MOD_PHP5. The problem occurs when 2 or more requests are served at the same time. PHP 4 doesn't have the problem but it works as CGI. On PHP 5 we rule out CGI because it is too slow. The problem seems to be related to exec/system/ functions family. Other scripts using system(), running .NET program, hang in the same way. Configuration: Windows Server 2003 Apache 2.2.13 PHP 5.3.0 ( PHP 5.2.10 has the same problem too) Any idea?
