Directory authority refuses vote fetch with "Too much data received from directory connection"
My directory authority just failed to make a consensus this round, and its notice-level logs include:
Jan 17 13:52:31.570 [notice] We're missing votes from 8 authorities (14C131DFC5C6F93646BE72FA1401C02A8DF2E8B4 E8A9C45EDE6D711294FADF8E7951F4DE6CA56B58 ED03BB616EB2F60BEC80151114BB25CEF515B226 585769C78764D58426B8B52B6651A5A71137189A 80550987E1D626E3EBA5E5E75A458DE0626D088C 49015F787433103580E3B66A1707A00E60F2D15B EFCBE720AB3A82B99F9E953CD5BF50F7EEFC7B97 23D15D965BC35114467363C165C4F724B64B4F66). Asking every other authority for a copy.

It looks like our current limit of 10MB is too low for fetching all votes at once?
(I guess a second question is: did we really mean for Tor to ask for 10+ megabytes from each of 8 places in parallel?)
