--qMm9M+Fa2AknHoGS Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hello Am curious what, if anything (besides heap) are tuneable in the VM? Also if people should make any adjustments to the FreeBSD kernel when using the VM as a heavily-trafficked application server. I have made a few adjustments to the kernel, specifically NMBCLUSTERS ... but I would appreciate any advice that would allow our VMs to scale and perform better under FreeBSD. Wondering how many of you are using RMI and the 1.3.1 patchset 5 build under Tomcat 3.2.3? Would like to compare notes. As a third, but much less important question -- I have not had any luck trying to build a VM with native threads using the 1.3.1 port/patchset 5. Are there any instructions towards this? We would like to build a VM with native threads (even if it is "alpha-quality code") to test it running under Tomcat first, then our RMI apps second.

We have had a problem with a JVM (not sure which one right now, but I could find out) where this issue was causing a silent death. The person who debugged this should be back in town this weekend, and I will ask him about it and try to let you know. <snip> > 1) Is the Linux 1.2.2 port thought to be stable on FreeBSD?

I have severe problems with the IBM JDK locking or not exiting. I have only seen the behavior in ant builds right now, but I have not tried anything else that is heavy duty with it. My few tests with hello world applications (even multithreaded ones) couldn't replicate the behavior. I have spent too many hours playing with it to not try to warn you off. > 4) Does someone have a cron script handy that could restart jetty > as a workaround? > 5) Am on the wrong track altogether? I would suck it up and use 1.2.2 native on FreeBSD or possible 1.3 native (although I am not brave enough yet). You will be without JIT unless you install one, but that might cause problems for you as well (with space and possibly reliability). OpenJIT was pretty easy to install, IMHO.
