Just had a production web/tomcat server panic with the following.
 	It was over a light weekend so no obvious load implications.
 	Machine has a GB of memory, runs 3.0_STABLE with an ACPI kernel,
 	and normally has plenty of swap free.

 	No crash dump (it had to be powercycled by remote hands). Anyone
 	have any thoughts as to what I could do to get more information?
