RE: Installing jakarta on linux RH9
The newest version (4.1.29) should be fine. If I recall, however, there
was a problem with Sun's Java Virtual Machine, and RH9, which used an
incompatible threading library.

Looking at the Red Hat 9 Release Notes, it seems that only JDKs prior to
1.4.1 fail. You are using 1.4.2, so you are not supposed to need the
LD_ASSUME_KERNEL setting ;-)
The problem comes from a new implementation of the POSIX Thread Native
Library. This new version corrects some deviances from the POSIX
standard, so applications that rely on these differences will fail.

Interesting. I wonder if that's all it is. Any wish to elaborate if you
are not using a connector to Apache? I was assuming everyone who was using
tomcat on such heavy loads would be using Apache in front.
BTW, if by any chance you're using the daemon scripts off my site, you
would be using the "LD_KERNEL_ASSUME=2.2.5"
I set that because you definitely need it on RedHat 7.3, and I don't have
a RH9 server in production yet. I'm probably also too afraid to change it
even now though.

I've never had anything die on me, and I have glibc-2.3.2-11.9, which
should be the version that comes on the RH9 installation media.
I'm using: Apache/2.0.46 (Unix) mod_jk/1.2.4 and Tomcat 4.1.27 with the
context reloading hotfix.
??
Not that I'm unhappy not having problems, but I'm curious as to why some
people have this problem and I don't.
Oh! Duh, I see it, now. I'm only using the CoyoteConector to allow
Apache to connect to Tomcat. I'm not using Tomcat as a standalone web
server.
(I decided to post this message anyway in case some people were not
clear what the problem is)

The problems are with the HTTP/1.1 connector (it dies after about one
day, regardless of the load). Also, there has been a GLIBC update which
could have fixed the issue, so if you keep your system fully patched,
you could be ok.

Is this accurate? I use RH9 with kernel 2.4.20/i686, JDK 1.4.2-b28
without any LD_ASSUME_KERNEL setting (that I know of).
Is this for a specific kernel version or architecture?

No, on RH 9, all VMs will actually need the LD_ASSUME_KERNEL env
variable (look in the archives for the details on the problems and the
workaround).
