Howdy, >We are not using runtime-controllable logging at this time. It seems that >log4j is the de facto standard, so I suppose that's what I'll try first. >How does the JDK 1.4 logging facility compare to log4j?
There have been extensive discussions on this issue on the log4j-user mailing list. That archive will answer your question. See here for a starting point: http://nagoya.apache.org/wiki/apachewiki.cgi?Log4JProjectPages/Log4jvsJD KLogging >Have you used any of the profilers designed for production use like >RootCause or jvmstat? I'm strongly interested in trying one of them out. I've used jvmstat and like it. But I don't profile much in production, only in dev/test, and on those environments I use OptimizeIt. >JRockit does not produce an hs_err file that I can see. It does do a dump >to catalina.out, which doesn't contain anything obviously useful to me. It >does output 'registers', 'stack', 'code' and 'loaded modules'. All are in >hex except the loaded modules. Well, that doesn't help too much ;( >I'm open to suggestions. We were pretty much a Windows shop until about 6 I would try the latest stable linux kernel. Wasn't there a threading library change a couple of kernel versions ago that several people complained screwed up their JVMs? >difference. Any other operating systems you would recommend? Things have been working very well for us on Solaris (8). But there's no reason you couldn't make it happen on linux. >of that.

What do you mean, tomcat doesn't really support? ;) Tomcat implements the servlet spec exactly with respect to SingleThreadModel.
