A. the file was removed from prereqscache by our "cleanup" scripts, I'm assuming, but it should not have been. It is likely not being marked as "accessed" correctly so the cleanup script thinks it is no longer in use.

I confirmed that the file was "prematurely" cleaned up on 11/17 approximately midnight

Its set up so that, supposedly, prereqs that haven't been used for 30 days get removed ... so, that part of script that should "touch" the file everytime it is used is probably not working right.

Well, this is embarrassing  ... I had put in the "touch" tasks in our ant scripts (so we could automate removal of old things, never used) and could not figure out why they weren't working ... I spent a few hours assuming it was an ant quirk ... then discovered I'd simply never "hooked up" the ant tasks to run! 

So, now they do. Using "stat <filename>" shows both the modification and changed times are changed when a build is ran (access time isn't ... but there's many problems using access time ... it either doesn't change enough, or changes too much, depending on how the file systems are setup).
