Timeout error

Sorry, something just went wrong in Launchpad.

We’ve recorded what happened, and we’ll fix it as soon as possible. Apologies for the inconvenience.

Trying again in a couple of minutes might work.

Using "Search" gives me "Timeout error" every time. Please fix it.

This is a periodic issue; it typically appears for ten minutes or so and then goes away again. It seems to be due to some kind of internal PostgreSQL maintenance task that locks the creation of temporary tables; when we've looked into it previously the lock seem to show up in any of the usual status tables. When we've discussed it in the past we concluded our best hope was to upgrade to a newer version of PostgreSQL (we're currently on 9.3) and hope that either that fixes the problem or at least gives us more information to go on.

@plamen-mbx: A search timeout, or a timeout that doesn't involve bug creation or modification, is unrelated to this bug. If you still see it, please provide details in a new bug report, quoting any OOPS ID.

We've deployed improved database triggers to production, so this should be much better now. If you still see persistent bug update timeouts, please file a new bug and we'll be interested to look into what's causing it.

We're still seeing this from time to time, although it feels less bad. https://oops.canonical.com/oops/?oopsid=OOPS-94b77a2c900519293c6cf20a0fa96c3d is a sample OOPS.
