Non recycled request

[Thomas Boniface <th...@stickyads.tv>]

Hi,

I can observer RecycleRequiredException (example below) in the catalina.out
of my application. This application relies on async servlets with some
async libraries, this exception can lead to strange behavior I guess like
mixing user cookies.

Is there some specific logs I could activate to isolate the use case
leading to this error ? Or some known deprecated behaviour that would lead
to this state ?
