[Xen-users] Dom0 crashes when serving java content on DomU

["Matthew Tice" <mjtice@xxxxxxxxx>]

Hello,  we're dealing with a very odd problem related to system crashes.
I have a Dom0 machine running OpenSuse 10.3 64bit with 128G ram.  One of the DomU's is SLES9 serving java-based web content.  The problem is that when I try to pull a web page from the DomU the Dom0 crashes.  The only way to bring it back up is with a hard reboot.

I've enabled various boot options to try to debug but I'm not getting any pertinent output.  On the Dom0 I configured the following options:
sync_console
loglvl=debug
guest_loglvl=debug
nmi=fatal
apic_verbosity=debug

I also redirected the kernel syslog-ng facility to log to a file (instead of console).  I don't get any info printed anywhere (console or log). 

An interesting side note is that I have another webserver that just serves static content also running SLES 9 and I don't have problems with that node.

To recap the system specs:
Dom0:

# cat /etc/SuSE-release
openSUSE 10.3 (X86-64)
VERSION = 10.3

# uname -a

Any help would be greatly appreciated
