to the same merchant into larger wire transfers. The actual transfers are then
done by **taler-exchange-transfer**.
+The AGGREGATOR_SHARD_SIZE option can be used to allow multiple aggregator
processes to run in parallel and share the load. This is only recommended if a
single aggregator is insufficient for the workload.
+
+The aggregator uses a special table to lock shards it is working on. If an
aggregator process dies (say due to a power failure), these shard locks may
prevent the aggregator from resuming normally. In this case, you must run
"taler-exchange-dbinit -s" to release the shard locks before restarting the
aggregator.
