Re: IIS6.0 - Error 500.13 Web server is busy

I am going to change everyone on the outside to pop accoubts for email.This
will eliminate everyone from using OWA. Then I can see what happens with
IIS.

Yes, OWA does sometimes crash IIS, but adjusting the timeout to 60 minutes
for 10 users shouldn't have that large an effect. On the other hand, the
only way to find out is to set it back to 15 mins for a while, and see
what happens.

Could OWA cause the IIS to crash. We adjusted the timeout for OQA to 60
mins from 15. We have about 10 users connecting to OWA through out the
day and constantly. Can that cause an issue.

Your IIS log files were 2.5GB each? And there is a new one generated
each day (the period is configurable)? That is astonishing.

I am using 4gig of ram. Here is the latest. I went in on Friday and
setup everyone up using blackberry to pull email with a pop account
setup. That completely stopped and blackberry action on port 443. The
only people left using 443 is for OWA. The server ran fine for 5 days
after. But this morning IIS crashed again. In the IIS logges are exchweb
connections but the log files dropped in size drastically from 2.5g to
400k.

I think you are going to have to use Task Manager or Performance
Monitor to see if your server's memory is being excessively consumed
over time. Exchange will want to grab as much memory as possible, but
it should not do so to an extent that will cause excessive paging. How
much physical memory is in the server? I don't think you mentioned
that yet.

You should only set it to Unlimited Connections if you have lots of
OWA users (i.e. thousands), otherwise too many hardware resources
will be allocated to IIS, and not enough to Exchange. How many OWA
users do you have? Is it just the 10 Blackberry users that you
mentioned earlier?

Sorry about that. I saying the server is not set to unlimited
connections. Should I check off unlimited connections. Also 98% of
the lof file is 443 communications to an outside ip addresses.

Thanks

I'm sorry, I can't make out your last sentence :-) . Are you
saying that you already have it set to Unlimited Connections, or
asking if you should set it to Unlimited Connections? Either
way, it depends on how busy you think your server is. It just
allows you to dedicate more server resources to IIS.

Can you see lots of logged lines with /Exchange and /exchweb in
that log file?

Lee,
I looked in the log files for IIS. I saw the same type of access
over and over port 443 with different users and the times are
just 30secs to 1 minute apart. That is the only thing I saw.
Should I look for something else. Also I checked that website
you sent me originally. THe instructiosn for performance tab, is
that to set unlimited conections. Is that what they are
suggesting.

Thanks
Scott

The Page File is supposed to be about 1.5 times the physical
RAM. I like to set the max and min sizes the same, so that the
server is not constantly resizing it.

I do notice that the pagefile is getting really big. The C
drive does not have a pagefile due to the size of the c drive.
The d drive is where the file is located. Also if I set a limit
on the pagefile I get a virtual memory error. If I let the
system manage the pagefile. It gets really big as high as 12gb
but after 24hrs that is when the iis give the error.

Hard to say what's going on, but it sounds like the server is
developing a resource problem. Try doing an IISRESET and see
if it fixes the issue. If it doesn't, then do a reboot.
Then, start your Task Manager, and see if the server's memery
is gradually being consumed. If memory usage does indeed
appear to rise constantly, then see which process is using up
memory at an ever increasing rate.

Lee,
Here are some of the issues. I have a Windows 2003
smallbusiness server with SP2 on it and Exchange 2003sp2
also. I ran all the updates on the server. I have a c drive
of 12 gigs of ram and 3 gigs of free space and an additional
d drive with data. I have AVG email scanner on the server.
Also a sonic firewall for the internet. I also have about 10
blackberry's that connect to the server using OWA to get
email. I scanned the server for viruses,spyware and rootkits
ALL Clean. This problem has been going on for about a month
now. The only way to clear it up is restart the server, or
restart IIS.
