You'll never be able to get that many threads going on a 32-bit Windows system. You need to scale it down to something reasonable (like the other config). > Shouldn't windows start to swap if the ram is full? You're not out of RAM, you're out of virtual space for the process. > In which memory-area does windows handle the memory which is used for > the threads? Is it shown in the taskmanager? No; I'm not aware of it being shown anywhere. > Can the OS take the mem which is still unused by the JVM (memMax- > memTotal) for handling threads or is it reserved for the JVM after > starting tomcat? It's reserved for the Java heap. > Due to problems with one of our webapps which sometimes does not close > the threads completely (they stuck in close_wait-state) we increased > the max threads of windows: So fix your webapp. > Does anyone have an idea to get rid of the exception?
