Could someone please help to explain the pattern below from an oncheck
-pt:

Yes, old OS, old Informix.....

Initial extent size is: 115000
Next extent size is: 25000

After the first next extent it allocates 3X8000 extents and 6X4000
extents and then the final added extent is 25000.

Why did it not allocate the 2nd next extent as 25000 and so on?

No extra dbspace has been added during the period.

The next extent size has not been altered during the period of growth.

Thanks,

Bernard.
