IdP Service hanging with v4.2.1 on Windows using MSI bundled Jetty (v10)

[Matthew Slowe]

Good day everyone,

We have a member of the UK Federation who's using the packaged MSI and 
recently upgraded from v4.0.1 to v4.2.1 and, since then, is seeing 
significant issues where, after a few days, the IdP service hangs. 
Sometimes it'll hang on 100% CPU (similar to the Jetty regression from a 
few months ago) and other times it'll hang on "idle" CPU but not service 
any clients.

The IdP in question isn't particularly exotic in any way (just a fairly 
vanilla config connected to AD). It's an identical pair of instances 
(with a load balancer) and they both hit a similar problem about the 
same time.

We've not had any other reports of this behaviour so I thought I'd pop a 
note on here to see if anyone else is suffering in silence … here's 
hoping! :-)

Thanks,
