Subject Re: 15 minute hang in IndexInput.clone() involving finalizers
Date Fri, 15 Dec 2006 17:23:03 GMT
I don't think there is necessarily a limit, but I am assuming there  
is some interaction between the finalizer or GC threads and adding  
new finalizers, which would require some sort of synchronization.

Do you use network resources in your app? I have a hunch this is  
somehow the cause.
