I don't find that at all. I find Forte runs considerably faster under Linux (2.2 kernel) than it does under Windows (2000 Server). Now that I'm running a 2.4 kernel, it should be even faster. > SUN -- Open Source your bleedin VM or else follow the old motto: > > WRITE ONCE DEBUG EVERYWHERE > > Get your act together ;) I'd rather see Blackdown's opensourced...Sun's sucks :) But, due to proprietary library restrictions, and restrictions from Sun's NDA with them when they developed the Linux port (it's a port of Sun's Solaris SDK), they can't opensource it, even if they wanted to. Anyways...all this doesn't matter...what matters is that JBoss is a great EJB container :) ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

All these years and still no decent java implementation and far too many issues for it to become a serious contender of any sort. Garbage collecting garbage. Give me a real lisp os anytime!

I haven't been using Sun's JDK 1.2.x/1.3.x under Linux because it's such a buggy piece of garbage. However, Blackdown's seems to work just fine, and doesn't seem to suffer from this memory leak you're referring to. But Sun's JVM isn't just buggy as hell under Linux...the same is also true of their Windows JVM. The Hotspot JPDA debugger doesn't work properly in either...have to run it in the classic VM all the time. JDK 1.4 doesn't seem to have any issues from Sun so far, however. ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

An OutOfMemoryException on Linux also occurs because of some issues Linux has with threading; this is also dependent upon the JVM you're using. We've been getting better results by using IBM's implementation rather than the one Sun provides. Win2k and the respective JVM's on Win2k doesn't show this problem.

RE: [JBoss-user] Memory Leak on Lunix!!!
27;s CPU get down to about 99% idle, the memory never clears up. I am forced to restart my server. I have tried this with two different databases and jdbc drivers (hsql and ms sql) and have gotten similar results, so I don't think it is a bug in the drivers. Am I using the pools incorrectly? Is that a pool configuration parameter that I should try?

HI , i'm running JBoss-2.4.3_Tomcat-3.2.3 on redhat linux 7.1. Jdk1.3.1_01 with j2sdkee1.2.1. I realized there seem to be a memory leak. i have not been able to pinpoint exactly where the leak is coming from at this point of time and am still investigating... currently, my application uses Jakarta Struts as well. the memory usage will slowly increment thru the weeks. at one point of time, the memory used by jboss was at 100MB! the java garbage collector seem to be working.. the memory did get restored back whenever the collector is working... at one point, after many weeks of not restarting Jboss, halfway thru a deployment, i encounter a out of memory exception. another colleague of mine has a diff and very simple application that basically read data from text file and update the database. his apps is running on another server altogether and he is having the same issue too. so much so that the infra-structure guys are complaining abt the memory usage. i also do not know if it is the way the applications is being coded? but the 2 apps and the developers involved do not work with each other at all. anyway, i will continue my investigation and find out more.
