Hi Matthew, These tests are only run sequential right? As in, Phab doesn’t build two diffs concurrently? If it used to pass then there might be something running on the server consuming memory. The pagefile is probably set to auto, but that means a certain % of the disk, if it needs more for some Reason it won’t grow beyond this maximum. Someone would need to login to see what’s going on 😊 Tamar From: Ben Gamari Sent: Saturday, October 22, 2016 20:39 To: Matthew Pickering; GHC developers; lonetiger@gmail.com Subject: Re: Windows Builder Disabled Matthew Pickering writes:

I have disabled the windows builder as it is consistently failing with the same error message.

From this log for example: https://phabricator.haskell.org/harbormaster/build/14430/

ghc.exe: getMBlocks: VirtualAlloc MEM_COMMIT failed: The paging file is too small for this operation to complete. 764ghc.exe: failed to create OS thread: The paging file is too small for this operation to complete.

Thanks for doing this Matthew!

Do you have any ideas Ben/Tamar? I can't see any recent commits which would have caused this failure.

Sadly no. This is quite odd. I'll need to look into this when I get back from Hac Phi. Cheers, - Ben
