Negative durations?

Could it perhaps be a dll relocation issue... that is fracturing the
contiguous space needed for the larger Java heap?

I've seen similar issues when 3rd party dlls that were pre-relocated
got loaded before the jvm starts..

The obvious causes: not enough contiguous memory to accommodate the heap. Fragmentation issues? We rebooted - no other stuff running - what other causes are there to produce such a VM start up issue?
