ocumentation 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.
