----------------------------------------------------------------
Hi Knut; your right about the extra diagnostics; for some reason I thought I
didn't see the stack in the report.. in any case, it seems the -1 page number
comes all the way from AllocationCache.java. I am not that familiar with that
code; is it possible it could ask for a page number -1 from there? I see
AllocPage uses -1 for INVALID_PAGE_NUMBER... I see allocPageNumber has this
Sanity code:
{noformat}
if (SanityManager.DEBUG)
{
SanityManager.ASSERT(isLatched());
SanityManager.ASSERT(
!isLast(), "next alloc page not present for last alloc page");
}
return nextAllocPageNumber;
{noformat}
Not sure how to interpret this...but maybe it's just a follow-on problem caused
by the first error.
