Hi everyone,
Did you ever experience dllhost.exe taking 100% cpu and cause the server not
responding?
The thing I can think of is infinite loop in code cause deadlock which I
tested on my computer. If this issue occurs occurs quite often on a
production server, what will you do to find out the problem?

An infinite loop in an ASP page can be the culprit.

To determine if ASP may be involved take a note of the PID of the
dllhost.exe processs. Then use the Component Services
MMC to look at the running COM+ applications. With the COM+ applications
node selected choose Status view. If it's one of the IIS apps then it's
likely an ASP problem.

IISState is a tool you can use to create a Dump of IIS activity. This will
list all the threads and if currently processing an ASP page which page it
is processing. A thread that has an inordinate amount of CPU and is
currently processing an ASP page is the likely culprit.

OR

you can review your recent code changes to see where a infinite loop has
been introduced ;)
