Hi Drew, I tried the patch and found it makes no difference. The current SUN JVM (1.3.0_02) gives the SIG11 as I indicated before. The latest IBM JVM (IBM build cx130-20010329) hangs around and eats up CPU time. It mostly eats system time (usage is about 8% user, 91% system). A normal kill is ineffective, I have to send it a -9 in order to terminate. > Also, are there any non commercial apps that demonstrate the problem? > Or at least things that I don't have to sign my life away to get > access to? Hmm, I don't use any. We are developing a large-scale JAVA servlet application, and that one provokes the SIG11, too. Moneydance, a shareware finance manager that I once evaluated (http://www.seanreilly.com), seems to run ok. If you really want to invest the time, you might go to togethersoft.com and download their product. They will send you an evaluation license as soon as you download the product, without any further request. But it's a big application, and you won't have any use for it unless you develop a large-scale JAVA application. -- Regards, Georg. ---------------------------------------------------------------------- Who in the world needs 2000 Windows?
