I got a message to moderate a message in the ubuntu-ar LP list. However when I try to access the page [1] I get a Timeout error (e.g. (Error ID: OOPS-1704EB927)). This is happening since past Sunday (at least).
TIA,
Mariano

The LibraryFileContent queries will be gone on edge, because that bug is fixed.
The librarian connection and reads are a considerable amount of time; we probably want to issue many connection-reads at once rather than serialising them all, or as curtis says batch it. Batching is almost certainly needed in extremis anyway, so lets do that first. |
