¿Qué causa este problema?

This is a single 'performance' check and therefore does not
describe a critical system status. It is neither necessary nor
time-critical to perform the steps described below, but they could
help improve the overall performance of your R/3 System.

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

The 'hit rate' of pages in the database buffer in percent is not
optimal
for read accesses. A rate of at least 95% is considered to be
optimal. A better 'hit rate' can often be obtained by extending
the database buffer (thus reducing the 'displacement rate' of pages in
the buffer). On the other hand, the ONCONFIG parameter 'BUFFERS' should
not be increased if this is not necessary in order to keep the
use of Shared Memory (i.e. main memory) within reason.

¿Cómo arreglar este error?

Check the read quality of the database buffer regularly with
'onstat -p'. If the percent value is constantly below 95%, try
increasing the ONCONFIG paramter 'BUFFERS'. You can assume 20% of the
physical memory as a approximate value for the buffer size.
As user 'informix', edit file
'$INFORMIXDIR/etc/$ONCONFIG' ('BUFFERS' = number of pages).
CAUTION: The change will only become active when the database has
been started up.
