We're looking into that problem. It's probably an occasional transient problem with tugelacache, the memcached replacement which was recently put into production. Approximately 12 hours ago, Domas implemented a workaround in MediaWiki which should minimise the effect of such errors. So hopefully you won't notice it anymore.
This intermittent problem has been around much longer than tugela has existed, hasn't it? Probably the same issue under memcached.
It seems to be more frequent now. The key expires after 24 hours (I thought it was a week, did someone change it?), and you'd expect to see the message cache stop working for a few seconds each time it expires. I always assumed it was just this problem. But we've had a sudden increase in the number of reports, and the problem persists for longer than a few seconds. Not exactly conclusive, it would be nice to have a theory about why this happens.
