Says DLL file is in use and can't be loaded until restart IIS

[Guest]

Hi;

I copied a new set of files over to my ASP.NET dir (and subdirs) on our test
server. This replaced every file for the app. When I first then tried to
bring it up, I got the below error.

After I bounced IIS, then it worked fine. log4net.dll is in the Bin
directory. What is going on here - this makes no sense to me.

It sounds to me like some process was still holding onto references to these
modules. Does it happen consistently?

Sysinterals.com has some utilities you can use to find out what processes
are holding onto what libraries. Sounds to me like some ASP.Net process was
just not behaving well...

Yes it happens consistently but when I use the sysinternals tools it does not
show another app locking it.

And in this case - how would another app have it locked so it can't be read
when I had just copied it to that computer? I was able to overwrite it in the
copy so at that point nothing had it locked. And the next thing I did was try
to bring up the website.

This is very weird.

Do you, by any chance, have the indexing service turned on ?
The indexing service has been known to cause errors like that one.

You might want to exclude the .Net Framework temp directory, the system temp
directory and the wwwroot and subdirectories from the indexing service's search.

Or, maybe, an antivirus system is interfering ?

Yes it happens consistently but when I use the sysinternals tools it does not
show another app locking it.

And in this case - how would another app have it locked so it can't be read
when I had just copied it to that computer? I was able to overwrite it in the

It is weird, especially since the sysinternals tool isn't showing what is
locking it down. Perhaps something more low-level is holding onto it - an
antivirus software tool, perhaps?

The indexing service is disabled and no anti-virus. This is a test server so
it's pretty vanilla.

Do you, by any chance, have the indexing service turned on ?
The indexing service has been known to cause errors like that one.

You might want to exclude the .Net Framework temp directory, the system temp
directory and the wwwroot and subdirectories from the indexing service's search.

Or, maybe, an antivirus system is interfering ?

Yes it happens consistently but when I use the sysinternals tools it does not
show another app locking it.

And in this case - how would another app have it locked so it can't be read
when I had just copied it to that computer? I was able to overwrite it in the
copy so at that point nothing had it locked. And the next thing I did was try
to bring up the website.

This is very weird.

It sounds to me like some process was still holding onto references to these
modules. Does it happen consistently?

Sysinterals.com has some utilities you can use to find out what processes
are holding onto what libraries. Sounds to me like some ASP.Net process was
just not behaving well...

Hi;

I copied a new set of files over to my ASP.NET dir (and subdirs) on our
test
server. This replaced every file for the app. When I first then tried to
bring it up, I got the below error.

After I bounced IIS, then it worked fine. log4net.dll is in the Bin
directory. What is going on here - this makes no sense to me.

I will try that next time. But I would hope that IIS/ASP does not trip over
something like that.

[Steven Cheng[MSFT]]

Hi Dave,

When you copy new content into your ASP.NET site, have you also copy the
Log4net dll and overwrite the original one? I suspect that the problem may
due to the shadow copied log4net assembly(in ASP.NET temporary folder) be
locked. Have you tried putting the log4net assembly into GAC to see whether
you'll suffer the same problem. also, when testing ,you can also change the
<compilation debug="xxx" /> to false so as to make the dynamic compilation
as release condition.

Sincerely,

Steven Cheng
