Description
Tomcat hang with 1.5.0-beta-b31 on Redhat Linux9

JDK version
=============
java version "1.5.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b31)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0-beta-b31, mixed mode)

Platform
=============
Linux jtg-linux13 2.4.20-8smp #1 SMP i686 i686 i386 GNU/Linux
glibc-2.3.2-27.9.7

Error message
=============
Tomcat hang on RedHat 9 in both C1 and C2 modes.

###@###.### 2003-12-18

We installed glibc-2.3.2-27.9.7 and unset LD_ASSUME_KERNEL.
And the problem starts to occur.

This problem is most likely caused by a race between
pthread_cond_wait() and pthread_cond_signal() on RH-9 with NPTL.

We will set up AS-3 and retest. Will update the bug report with
the status on AS-3 box.

###@###.### 2003-12-18

The problem is not reproducible on AS-3 box. That proves Hui's theory
that the bug is in RedHat 9's kernel.

Comments
EVALUATION Likely an NPTL or kernel futex bug. Will try RHEL-3. ###@###.### 2003-12-18 The problem does not happen on RedHat AS3.0. it's not a bug from our (J2SE) side. ###@###.### 2004-03-08
