Post subject: Multiple copies of dllhost???
Archived from groups: microsoft>public>inetserver>iis (more info?)
I am running 2 separate w2000 servers with identical files for backup. While
the files are identical (updated nightly) the iis was set up manually on each
so there could be some differences there but they are not obvious. Each server
has 9 operating websites.

The problem is that one server is using more memory.

I think I have tracked the problem down but not a solution. With reference to
the task manager... Server1 has 1 DLLHOST.EXE for the IWAM_SERVERNAME while
Server2 has many... and they continue to add with the resulting loss of free
memory.

The only way to clear these it to restart IIS. Server1 seems to be sharing the
DLLHOST.EXE IWAM_SERVERNAME while Server2 seems to create a new one for each
website as soon as a hit is made on global.asa.

Why is one server sharing and the other not?

Is this really the problem or am I missing something?

Any info or pointers appreciated.

Check what the application isolation level is for each website.

If they are set to High isolation, then each website will run in it's own
dllhost.exe, but if one website has a problem (eg memory leak or whatever),
then only that website will be affected.

If they are set to Medium Isolation, then there will be one dllhost.exe, and
all websites will run in that process (but they are still isolated from IIS
itself, which runs in inetinfo.exe, so a website crashing can't bring down
IIS itself)

Cheers

Thanks Ken...

Isolation level??? Is that the same as "Application Protection" in the iis
manager? I see 3 levels there... low/medium/high

Yes.

Check what "application protection" leve each website is running under. All
sites running in "Medium" will run in the same dllhost.exe (there will be
one dllhost.exe for all the sites). Sites running under "High" will have a
separate dllhost.exe

Cheers
Ken
