No, it's all done on a local (ZFS) file system (I don't even have any NFS volumes mounted), although I *am* using a separate build tree. Geoff On 06/28/2013 10:30 AM, Simon Marlow wrote:
Geoff - is it possible that this problem might be caused by time skew between NFS servers? Are any parts of the build, or files accessed by it, on NFS?
Cheers, Simon

My only claim was that I have a set of steps that can reliably reproduce an error on my system, not that these steps will reliably reproduce it on an arbitrary system, e.g., yours.

So, to be clear, you see recache errors sporadically and for different sets of tests across different runs, and you are running validate with no extra arguments, single-threaded, on a Linux x86_64 system with an ext4 file system? Yes, except I would say "very often" instead of "sporadically". I'm not sure about single-threaded. I run validate without any parameters - doesn't it use more then one thread in this case?
It looks like running validate without any parameters will use 2 threads.
I've pushed a fix (I hope) for this issue. Could you check and see if it's fixed for you now?
