Public bug reported:

Multiple users on the forum have reported deadlock issues when there are
many users (20-30) copying pages & collections at the same time. See
https://mahara.org/interaction/forum/topic.php?id=7309&offset=0&limit=10

Note that 20 to 30 users is around the number you'd hit if you're
running a whole class of users through a training session at the same
time.

The three reported cases of this are all in 15.04, so it may be a
problem introduced in that version.

The problem has been reported in both Postgres & MySQL.
