What were you doing at the time that triggered the error?

Probably caused by a corrupt session table in the database. Just wait a few minutes and/or restart your browser.

I tried again after 2.3 seconds and the error has gone.

<OffTop>Nice example to show for people thinking hashes never have collisions. The same for GUIDs.</OffTop>

That usually only happens when the hashes are generated badly. The hash functions themselves are mostly okay. If the hashes are done correctly even MD5 takes a lot of effort to create a duplicate.

Definitely. It’s often enough to have the same source data (including salt) which might even be the case this time. It just seems phpBB developers didn’t think enough about that, and having hash being a primary key is obviously a bad idea: due to birthday problem we don’t need 2^128 hashes for a collision to happen and due to obviously uneven distribution of the source data the probability of collision increases significantly.
