The JDK is already installed, i made some heap dumps when the problem started but could not find anything unsual there.
The Ignition service restarted two days ago (i am using a trigger in the wrapper.conf on OutOfMemory exceptions). I made a heap dump immediately after the restart and two times a day since then. At the same time, i recorded the Windows memory footprint. You can see that the private data (Java heap) stays constant but the windows heap is continously increasing.
The zip file in this link contains two heap dumps, one directly after the restart, the second one from two days later. Maybe you can find something that i missed.
