#24534 [Opn->Fbk]: instability : iis is reseted automatically frequently
ID: 24534
Updated by: iliaa@php.net

-Status: Open
+Status: Feedback
Bug Type: IIS related
Operating System: Win2k
PHP Version: 4.3.2
New Comment:
If the problem is due to a memory shortfall try the following test.
Make a simple php test script and then using ApacheBench or httpref try
sending a large number of requests to it. Meanwhile monitor the memory
usage to see if it continues to increase until eventually there is no
memory avaliable.

One of my customers has the same problem since upgrade from Php 4.1 to
4.32. The error occures 3 - 10 times a day.
I've tried a lot: Installing Php on three different machines with a
clean OS (and different Php versions > 4.2), playing arround with
IIS-settings, enable and disable Zend-Optimizer.
But problem is still there.
Now I use Windows 2003 Webserver Edition. IIS doesn't restart abnormal
(because he now uses a seperate worker process), but in the
Event-Viewer I found this (once again 3 - 10 times a day):
A process serving application pool 'DefaultAppPool' terminated
unexpectly. The process id was '...'.
The process exit code was '0xc0000005'.
When this error occures the following message is displayed on browser:
"Php has encountered an access violation at..."
When I reload the site everything works fine.

So far the snapshot didn't help. IIS keeps resetting (1-2 times a
day).
BUT : I found out, that before it happens, the available System Memory
goes rapidly down. Does this information help in any way?

And make sure you remove ALL existing PHP related dlls/binaries from
your system before installing the new version.

My description seems to give a wrong impression of the situation :
It is definitively NOT a "normal" thing to happen if the web service
resets several times during a day.
This behaviour just started when we upgraded from php4.1 to 4.3.2, so
to me it seems to be related to the new version of php - Am I wrong?
Problem is, that I'm currently not able to trace the reset to certain
situations. Can someone recommend a monitoring tool for this situation?
