> Hello all,
> 
> I have an IdP (v2.3.0) that is configured to load remotely configuration files and reload them every
> 24h. Federation's metadata are also configured to be loaded remotely by using
> FileBackedHTTPMetadataProvider.
> 
> Although IdP seems to work just fine, I think that there is a bug in reloading procedure. I 've
> noticed that, every time that IdP is checking for metadata, there are too many requests and also that,
> day by day, this number is constantly increasing.
> I suspect that this is happening because every time relying-party.xml is reloaded a new background
> process is created for checking metadata without "killing/re-using" the old one.
> In the attached file there are configuration and access.log snippets from a test that I run yesterday
> (relying-party.xml is reloaded every 2min, metadata file is checked every 1min), in order to show the
> constantly increasing number of requests.
> 
> Having IdP running for 3 months, reloading relying-party.xml every day and checking metadata every 3
> hours produces a large number of requests to web server that holds metadata...
> 
> Any thoughts, comments, suggestions?
> Thanks,
> Pavlos
