Bug#522046: Crash in DomU when running java
Package: linux-image-2.6.26-1-xen-686
Version: 2.6.26-13lenny2
When I am running with this kernel as a 32-bit Lenny DomU on a 64-bit
CentOS 5.2 Dom0, the DomU crashes whenever I try anything intensive with
Java. I have tried openjdk-6 and sun-java6, both exhibit the same issue,
for instance when performing a "dpkg-reconfigure" - crash messages
below.
If I boot using an older kernel, e.g. one from Etch
(linux-image-2.6.18-6-xen-686, 2.6.18.dfsg.1-23), this doesn't happen.
un linux-image <none>
(no description available)
un linux-image-2.6 <none>
(no description available)
ii linux-image-2.6-xen-686 2.6.26+17
Linux 2.6 image on i686, oldstyle Xen support
ii linux-image-2.6.18-6-xen-686 2.6.18.dfsg.1-23
Linux 2.6.18 image on i686
ii linux-image-2.6.26-1-xen-686 2.6.26-13
Linux 2.6.26 image on i686, oldstyle Xen support
By DomU configuration looks like :
bootloader='/usr/bin/pygrub'
memory = '1024'
root = '/dev/xvda ro'
disk = [ 'phy:mapper/java-dev-1-root,xvda,w',
'phy:xenimages/java-dev-1-swap,xvdb,w' ]
name = 'java-dev-1'
vif = [ 'bridge=xenbr0,mac=00:16:3e:5a:95:18' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
The following is an example of the error messages that appear on the
DomU console, these can be triggered on-demand by issuing a
"dpkg-reconfigure sun-java6-bin" for instance.
