PHP 4.3.4 Windows Binary - No extensions enabled
I have been fighting this battle on a number of servers and finally found
the culprit.
PHP4isapi.dll is constantly causing exceptions that eventually after awhile
cause the HIGH ISOLATED memory websites in IIS 5 to become unstable where it
eventually causes the dllhost.exe (high isolated memory for a website) to
start crashing every 6-12 hours and produce the follow error in Event Viewer
EVENT ID 37
Out of process application '/LM/W3SVC/6/Root' terminated unexpectedly.
I ran a program called IISSTATE to watch the threads and found that with
php4isapi enabled, everytime a PHP script executes, it produces 3 exceptions
(1284.166c): Unknown exception - code 8001010e (first chance)
(1284.10e4): Unknown exception - code 8001010e (first chance)
(1284.10e4): Unknown exception - code 8001010e (first chance)
If I reconfigure IIS to use php.exe, and unload the memory for the site so
that it starts using the new php.exe setting immediately, then the Unknown
Exception message stop being logged by IISState, when I change it back to
use php4isapi.dll, I immediately start receiving these exceptions, 3 at a
time for each time a php script is executed on the server.
Anyone know why php4isapi.dll is doing this? Its the version that came with
4.3.4 windows binary zip release.
I've reproduced this problem on 3 different webservers. This has been a
problem even with earlier versions before 4.3.4
A search on google.com for php4isapi.dll problems results in tons of people
having similiar issues with it like this one:

I know that there was some guy recently, about a month ago or so, that
posted a message here about some problems with isapi, and he could "solve"
the problem by configure php to run as an CGI app - just as mentioned in the
google reference you gave. But he also stated - as in your references - that
running phg as CGI did create a performce hit for his application.
I've configured php as a CGI application on win2003 server with IIS6.0, and
in my ingorance about this matter I don't see any direct performace problem
with my apps, but this might be due to that most execution time (>95%) is
spend in the RDBMS it self.
I don't think this information will help you that very much, but it migt be
worthwile to scan the history of this e-mail list to see if you can get any
clues on how to dig further in the mud.

Hi,
I can feel your pain. I had this problem too.
The only high performance stable solution for IIS that i know is FastCGI.
