Hey,

Well, there was a case when in case of some rogue apache not getting (or not willing to get) messages object. I didn't track it yet wether it was limited to one server or was it cluster-wide trouble. I could not track any troubles with tugelas, using mctest. There could be file descriptor troubles or similiar stuff.

I did a trivial change, now in case of troubles does not override existing messagecache object with "loading", but silently loads that object itself. There are two things I'm going to do - track the troubles in tugela and/or memcached-client/apaches, and using Turck MMCache for frequently used large object storage.

Cheers, Domas

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.
