Hi
I having a bit of a problem on our Web server, we are facing this issue for
almost more then 5 years now, we have done lot of research on this many
google query and reples most of them refer to infinite look, open loop etc
etc in programming we have check everything no programming issue at all all
pages worksgreat... some time in months some time in week some time more
then 2-4 time in week DLLHOST flakes out and utilize 100% CPU which causes
all sites to stop working even we can not get in to server through vpn to
kill the process some time we manage in early stage where its start doing
this and kill from task manager and all back to normal, some time need hard
reboot.. so ideally we are loosing business. as per our programmer he had
tried moving the site to diff server also but same issue there so here is
dome word from programmer,
A classic asp page is written on Jscript, uses ADODB.command. First time
deployed in 2003 and works usually fine. Occasionally this page is causing
dllhost.exe to run at 100% cpu.
All internal attempts to replicate the problem during tests failed. Last 5
years of monitoring show that the page actually finishes working and returns
all the output but doesn't close the http connection and keeps the
dllhost.exe running on 100% cpu.
Your help to resolve this issue will be highly appriciated.
Thanks

windbg, sos, and adplus are your friend here. when at 100% cpu, use adplus to
connect to the process and either debug directly or create a crash dump.

Hello Group,
I have had an issue on my server for a long time and what ever I have tryed
I just cant fix it.
I run mySQL and IIS, and my server will crash every few days because a file
on the server called DLLHOST.EXE has taken all the memory, and the mySQL
goes off line.
I close all of the record sets, and all of the Text files I read, as below

I've got a Windows 2000 server running with about 50 websites on it, all
running ASP scripts. I've noticed that the servers CPU usage gets up 100%
sometimes, caused by dllhost.exe, which I'm certain is a hanging ASP script
somewhere on the box. Probably an on error resume next line that doesn't go
anywhere when an error is an encountered. Anyways, I'm not sure if there's
a way to isolate the website where its originating, or even the...

Hi All,
I'm using the .NET performance counters to calculate the network
utilization. But this value exceeds 100%.
In most of the cases, it is very similar to the one shown in the
task-manager. But when I try to measure the network utilization with a
particular utility that sends large data, then the values that I get
exceed 100%. Even in the task-manager it shows similar graph (graph

Hi all,
Today, an interesting thing happened to me. When I am doing the test of an
asp program, one of the pages(which I submitted several ten times before, no
problem at all) caused our server cpu rising to 100% and I reset IIS and
submit that page again and same thing happened again, and then reset IIS
again and it happened again, the process caused this is dllhost.exe.
Thinking about what's the difference this time from what I submitted...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
