Documentation for system log message BS 0 :
A memory overflow in the buffer synchronization
occurs in production systems extremely rarely. It is
usually caused by a transaction that has changed a large number
of buffered objects.
If an overflow occurs the affected buffers are reset on external
application servers. The possible causes of the overflow are
logged in the associated trace file. In most cases the cause is
buffered tables. You should consider whether these tables really
need to be buffered, that is whether the number of read accesses
far outweighs the number of write accesses. It may be best to shorten
the database transaction by using quicker, consecutive
COMMIT commands.
