Red Hat Bugzilla – Bug 446169
Java VM crash when using threads
Last modified: 2009-01-09 01:29:58 EST
Description of problem:
Was creating a multi-threaded program. The code just starts a new thread and
immediately joins it. Once the Java VM crashed. Other times it just runs very
slowly. I'm using Fedora Eclipse.
Version-Release number of selected component (if applicable):
java-1.7.0-icedtea.x86_64 126.96.36.199-0.19.b21.snaps installed
I only got the crash once. Other times, it just runs very slowly. It responds
very slowly to pause / stop debugging requests. There is plenty of free
memory. One CPU core appears to be fully utilized (htop reports both at 50%)
Steps to Reproduce:
# An unexpected error has been detected by Java Runtime Environment:
# SIGSEGV (0xb) at pc=0x00000035f9a72bc9, pid=10112, tid=1074792784
# Java VM: IcedTea 64-Bit Server VM (1.7.0-b21 mixed mode linux-amd64)
# Problematic frame:
# C [libc.so.6+0x72bc9]
# An error report file with more information is saved as:
# [ timer expired, abort... ]

I just installed java-1.7.0-icedtea-debuginfo.x86_64 in case it crashes again.
I am using java 1.6 on F9 now. I'm sorry that I can't assist with this any
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
