Hi,

Our EPrints 3.1.0 server seems have an excessive amount of cache tables (it
was the same on 3.0.x). Whenever the server's been running for a few weeks
without any restart, the database starts to fill up with a huge load of
cache tables.

After a while the server starts to hang. Symptoms are: all apache threads
seem to be stuck in some infinite loop, an apache restart mostly fixes the
problem though sometimes even mysql needs to be restarted. Not sure if this
is related to the excessive amount of cache tables though.

Does EPrints clean these cache tables up automitically? If yes, why is it
still growing over time on our server, did I perhaps forget to configure
something (like a cron script)? What triggers the cleanup actually?
