Incorrect behavior (everything from a crash to more subtle misbehavior)
The dart2js-full-windows slaves are running out of space on the C: drive because crashes of IE leave a copy of the open tab information for IE's automatic crash recovery.
The directory C:\Users\chrome-bot\AppData\Local\Microsoft\Internet Explorer\Recovery\Active (or High\Active) contains tens of thousands of these files, some of which are > 1 MB.
We discovered this on vm195-m3, because for some reason it has a 45 GB C drive, instead of the 60 GB C drive on the other slaves.
Automatic crash recovery can be disabled in the IE options, but it still writes these files to the directory. The only way I found on the Internet to stop this is to use ACLs to make the directory unwritable:
icacls "%UserProfile%\AppData\Local\Microsoft\Internet Explorer\Recovery" /deny *S-1-1-0:(OI)(WD,AD) /t

I'm currently deleting these files, which should give us about 3 months before it happens again.
