I agree with an eariler comment that = threads are probably a serious problem here. I have no idea whether it is a problem with FreeBSD, = linux-threads/emulation or the jdk's themselves.

Hi,

4.2 and 4.3 FreeBSD on two = 2xcpu smp=20 systems. linux-jdk1.3 and linux-jdk1.4beta.

I have had such odd = results with java=20 on FreeBSD (somethings run and others dont) that I decided to = run a=20 test. The test was to run a standard piece of software against these two = jdk's.=20 That being Jakarta Tomcat 3.2.2. Cant get more standard than that. It is = the=20 standard actually. Interesting that it didnt work. Hotspot blows chunks = on a=20 regular basis ( java.core's). I agree with an eariler comment that = threads are=20 probably a serious problem here.

I have no idea whether it = is a problem=20 with FreeBSD, linux-threads/emulation or the jdk's themselves. Here is = an=20 obvious question. Do the developers of the "core" code = (kernel/emulators/jdk's=20 etc) bother testing against something as basic as this? Is this a = problem=20 that is being fixed in 5? Should I be running 5? Is FreeBSD doomed to = serving=20 applets or simple servlets? (It's dead if it is IMO).

Something isnt right here. = Any help=20 would be appreciated. (I'm mainly talking to the developers of the core = code I=20 think).

Thanks

Jim
