Was verursacht dieses Problem?

By setting this database configuration parameter (CHNGPGS_THRESH), you
determine at what number of changed pages in the buffer pool should
these be written asynchronously to the database. This is done by the
Page Cleaner.

Systemantwort

If you set too high a value for the parameter, it may be that pages are
not written to the database on time. These pages are then written
(before they are replaced because of lack of space) synchronously; that
is, the application must wait until the page that is to be replaced has
been written.
On the other hand, if too low a value is set for the parameter, the
system will write pages to the database unnecessarily often.
