I think I at least identified the problem. Thanks to my Solaris OS, I
can see how many threads are being used. And with a quick stress-test,

something is leaking :)
We hunted for this on Linux, but couldn't find anything, as we only saw
a bit of memory leaking. Now on Solaris I can clearly see the threads
