Comment 8 for bug 302798

The periods when the timeouts happen are definitely correlated to the staging updates, and they don't happen at all when the staging database is not updated. The updates do just enough I/O to flush all but the hottest data out of the filesystem cache.

To stop the timeouts from happening over the holidays, staging database updates will be halted. We plan to move old data out of the way after the holidays, which should also bring some short-term relief.
