Comment (by mestriga):

 This change could have caused it:

 "Lower the file limit in consdiffmgr, to support seccomp2":
 https://gitweb.torproject.org/tor.git/commit/?h=maint-0.3.1&id=466e9140888f0a6a504dc642a0426bd2352f0490.

 If this problem is happening only on windows, reverting cache_max_num to
 its previous value on Windows builds by means of a #DEFINE directive
 should fix it.
