Did you understand the RMI thing instead? My wild guess is that you're running your program in a container of some sort (e.g. an application server), or using a framework like Spring that allows to publish services via RMI. Then you might not find any mention of RMI in PRISM's sources.
Thanks for your suggestion. I'm not using any sort of container, and PRISM isn't either (to the best of my knowledge -- it's a very big system). I think Mark is probably right and it's the Oracle/Sun jvisualvm profiling stuff that's somehow causing this, but I can't tell.
I'm going to see if I can grok Eclipse well enough to use that to profile: I know my code (heuristic search code) is bogging, probably choking on memory or somehow thrashing. Unfortunately, the jvisualvm just shows all these RMI threads as hot spots, making this a kind of Heisenbug. :-/

Every call to Function.execute() will run in the invoking thread, so unless the invoked call path explicitly spawns a new thread, there should only be as many threads present as you are invoking. LispThread is essentially a wrapper around a JVM thread that maintains a multi-threaded consistent view of the singleton Lisp environment as that JVM thread executes Lisp code. As for “catch the result”: do you just mean act on the return value, or are you using a Java catch clause? Any chance you can put the source up publicly for me to have a shot at running it? -- "A screaming comes across the sky. It has happened before but there is nothing to compare to it now." _______________________________________________ Armedbear-devel mailing list Armedbear-devel@common-lisp.net <mailto:Armedbear-devel@common-lisp.net> http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel
