:Anyway, I have a simple program that mmap()s a 1Gig file into memory,
:madvise()s it that it will be doing random access. If I quit and restart
:this program a couple of times (yes, it close()s and munmap()s the segment),
:my system will hard lock. By dropping into DDB once I found that it was
:stuck in 'vm_somethingorother_choosepage'. Does this ring any bells? Should
:I try to stop my system again?

David, can you email this program to me please?
Also, which FreeBSD release does this occur on?
I've got about 6 mmap-related bugs on my plate at the moment. 3 of them
have been identified ( that is, I know why they deadlock the machine ),
but none have been fixed yet.
