--- Comment #5 from Violeta Georgieva <violet...@apache.org> --- Hi, I succeeded to reproduce the exceptions from this issue [1]. 1. Request a file with such a length so that "send file" is used. - just before serving the file [2], delete it, thus it will cause the processor to be released and recycled. As a result this processor will be added to the "recycled processors" [3]. - after this while finishing the response the processor will be released and recycled once again [4]. This will add the processor again to the "recycled processors". As a result one and the same processor will be in the "recycled processors". 2. Now request twice. One and the same processor will be provided for the two different requests [5]. I do not know whether you scenario is similar. If you can describe your scenario it will be helpful. So currently we are using org.apache.tomcat.util.collections.SynchronizedStack<T> which does not guarantee uniqueness of the elements.
