#45786 [Com]: FastCGI process exited unexpectedly

ID: 45786 Comment by: karelevzen at gmail dot com Reported By: karelevzen at gmail dot com Status: Assigned Bug Type: CGI related Operating System: Windows Vista Ultimate x64 SP1 PHP Version: 5.3CVS-2008-08-10 (CVS) Assigned To: dmitry New Comment: If this helps, I have created a dump 6 seconds after executing the page. Thread 0: ntdll!NtDelayExecution+15 kernel32!SleepEx+62 kernel32!Sleep+f php5ts!php_get_inf+1eaf php5ts!execute+cc5 php5ts!execute+6130 Thread 1: user32!NtUserGetMessage+15 user32!GetMessageA+a2 php5ts!zend_timeout+1a8 Another thing I found interesting is, that upon the request, a php-cgi.exe is created and does nothing. After the timeout, in the same exact moment, a new php-cgi.exe is created, the old php-cgi.exe is destroyed and the page is rendered. Is this behaviour normal or should I futher investigate this strange process? This second php-cgi.exe process is destroyed upon refresh and the display of the IIS error message.

It behaves the same, eg. it loads the content, then keeps "loading" for some time (faulty php module). This time, the GUI error message DOES NOT APPER, but when I hit refresh, it displays a IIS error message stating: HTTP Error 500.0 - Internal Server Error Module FastCgiModule Notification ExecuteRequestHandler Handler PHP Error Code 0x8007000d After another refresh the page again loads, keeps on loading for a while, than, after another refresh the same error appears. IMHO it's the same problem, but this time IIS realizes that an error had occured when the second request is received. Due to the GUI error not showing, I cannot send you a crushdump. ------------------------------------------------------------------------ [2008-08-18 11:03:30] dmitry@php.net Could you please retest CVS. ------------------------------------------------------------------------ [2008-08-13 14:22:26] jani@php.net Dmitry, something fishy with request shutdown in fastcgi? Note the ini options used by the user: cgi.force_redirect = 0 cgi.fix_pathinfo=1 fastcgi.impersonate = 1 ------------------------------------------------------------------------ [2008-08-13 10:32:13] karelevzen at gmail dot com So hey, I managed to find a 5.3 release WITH debug files at http://downloads.php.net/pierre/ !

Am I missing something? The debug pack contains runnable PHP, no pdb files. I cant find pdb files for the current 5.3 snapshot. Try it yourself. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
