IIS appliction pool Recycling drops DLL-references

I'm not sure if this is the right group, but:

When the IIS performs a recycle on an given Application Pool, the
website on this pool seems to loose references to third-party DLL-files
in the bin-folder.

We then have to start/stop the site go get it to work.

The recycling is now disabled to avoid the issue.

Any ideas as to why?

a recycle only unloads the appdomain, it does not restart the worker
processes. this means unmanaged dlls are not unloaded. when it reloads
the dll are reloaded, if your 3rd party dll don't support a reinit then
they will not work.

Thanks a bunch for your reply!

What does it mean for dll to support a "reinit". How is this defined?
