[Fedora-xen] Domain 0 reboot when network flow is heavy

Hi All, I am not sure about this, just wondering anyone has the similar situation with me:: I was using scp command on a remote server, copying a 20G file into Domain 0 server. the speed displayed is around 8Mb/s waiting... waiting... at 67%, it stopped, why? because Domain 0 reboot..... I check the log, nothing useful. I guess it is because the network flowing, because the domain 0 has been running for 3 weeks until today I do the copying. I attached some info, please give me some advice, thanks a lot!! xin [root@XenServer xen]# uname -a Linux XenServer 2.6.18-1.2798.fc6xen #1 SMP Mon Oct 16 15:11:19 EDT 2006 i686 i686 i386 GNU/Linux [root@XenServer xen]# xm info host : XenServer release : 2.6.18-1.2798.fc6xen version : #1 SMP Mon Oct 16 15:11:19 EDT 2006 machine : i686 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 1 cores_per_socket : 4 threads_per_core : 1 cpu_mhz : 1600 hw_caps : bfebfbff:20100000:00000000:00000140:0004e33d:00000000:00000001 total_memory : 4094 free_memory : 0 xen_major : 3 xen_minor : 0 xen_extra : .3-rc3-1.2798.f xen_caps : xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p xen_pagesize : 4096 platform_params : virt_start=0xf5800000 xen_changeset : unavailable cc_compiler : gcc version 4.1.1 20061011 (Red Hat 4.1.1-30) cc_compile_by : brewbuilder cc_compile_domain : build.redhat.com cc_compile_date : Mon Oct 16 14:34:31 EDT 2006 xend_config_format : 2 /var/log/xend.log [2007-06-24 01:08:55 xend 3125] DEBUG (DevController:149) Waiting for 51712.
