      1. Setting Project (described in detail below)
      2. Repeatedly send Rest call using SoapUI
      3. Change window time and hot deploy in 1m(window time)
      4. Check Count. But.. return wrong result count. (rower or higher)

      I tested rule contain sliding window.

      But when i deployed the rule to change window time,

      I failed hot deploy during window time, and some data lost.

      My drools fusion is 6.2.0 version

      I attached trace result.
