---++How can I find on which table deadlocks occur?
---+++What?
How to understand lock contention situation for your Virtuoso instance.
---+++ Why?
There are time where clients make assumptions about locking that contradict the default isolation level of a Virtuoso instance (typically: read committed). Being able to view lock content information can be helpful in diagnosing such conditions.
---+++ How?
<verbatim>
SELECT TOP 10 *
FROM SYS_L_STAT
ORDER BY deadlocks DESC
