I'm in a similar situation, except that in our (my) case the java prog. is part of a product loadbuild environment. Though it's quicker on FreeBSD, it runs reliably on Linux. > that can be used to crash to Linux vm under linuxlator, maybe > this could be discussed on freebsd-emulation or -current mailing My gut feeling is that it's a race condition - sometimes the signal handler gets registered in time to catch the exception, sometimes it does not. Though since I know very little about the linux threads model and more importantly, how it's implemented in the Linuxulator, I can only speculate. Anyone out there an expert on this ? :) :) > list ?
