This is because of bugs in the node that cause threads to get hung and never return to the thread pool, so that it is forced to create more and more overflow threads to satisfy the ticker. Switching to a thread pool that doesn't create overflow threads won't solve this. It'll just make the node die sooner when the ticker can't get any more threads. In a functional node, overflow threads would disappear rapidly as connections were killed to free up threads. -tc > Also almost no connections are successful under load. > > The new ThreadFactory should fixes these problems.
