Help with IISState interpretation

TheMSsForum.com: The Microsoft Software Forum

Hi,

Im calling an ASP page (do_convert.php) which

1. uses the majodio FTP component to GET some files
2. instantiates an ASPExec object which calls an .exe file (pfcl.exe)
which
3. uses the PowerPoint Presentation Component to carry out a
conversion and
4. uses majodio FTP component to PUT converted files back to the
remote server

About twice a day my Event Log displays the following error:

Event-ID: 26
Application Popup: dllhost.exe - Application Error: The exception
"unknown software exception" (0xc0000024) occurred in the application
at location 0x778abf48.

and after about 8 of those IIS hangs up and only a reboot solves it:

The HTTP server encountered an unhandled exception while processing
the ISAPI Application ' ntdll!RtlRaiseStatus + 0x24
ntdll!RtlpWaitForCriticalSection + 0x160 ntdll!RtlEnterCriticalSection
+ 0x46
asp!TS_RESOURCE::Unlock(void) + 0xAAC4
asp!HttpExtensionProc + 0x3D
'

The W3SVC1 log shows "ISAPI request failed":

2004-08-18 09:07:38 80.129.53.24 - 192.168.0.2 80 GET
/xxxx/do_convert.asp
r=2&id=114&f=mainz05.pptOut-of-process+ISAPI+extension+request+failed.
500 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.2;+.NET+CLR+1.1.4322)

Im having trouble finding out which component actually causes the
error.

Below are the links to the IISState logs of

--> inetinfo.exe http://194.152.172.170/mk/iisstatelogs/IISState-1504.txt
--> dllhost.exe 1 http://194.152.172.170/mk/iisstatelogs/IISState-2528.txt
--> dllhost.exe 2 http://194.152.172.170/mk/iisstatelogs/IISState-2568.txt

MY QUESTION: How do I find out which component (ASPExec, Majodio,
Powerpoint DCOM or Pfcl.exe) causes the exception???


Thanks for your help!

The logs do not show anything amiss. You will need to run IISState against
the DLLHost.exe(s) only (since that is popping up):

iisstate -p <pid of dllhost> -sc <enter>

You can run multiple instances (one for each dllhost.
