Old posts don't seem to be showing up.

For some reason, posts that are sufficiently old don't always show up. For example for the CKCC collaboration on medbook.ucsc.edu, there are following posts:

db.posts.find({collaboration:"CKCC"}, {collaboration:1})
{ "_id" : "CBPZxdpfTqzC2sPc2", "collaboration" : [ "[email protected]", "CKCC" ] }
{ "_id" : "T5yf2RTN36Lwu7meP", "collaboration" : [ "CKCC", "[email protected]" ] }
{ "_id" : "KnMpQ6vMKLqARTHZJ", "collaboration" : [ "[email protected]", "CKCC" ] }
{ "_id" : "D8t6nJrAHusqrCxNN", "collaboration" : [ "CKCC", "[email protected]" ] }

But only one shows up.

Can't reproduce on cloud-hosting build c629098 .

Artificially aged posts continued to appear in /collaboration/collabname view.
Imported the example posts and they all appear as well.
