it is not really useful to have two paging spaces anymore. The idea is that you dont use paging space, but use more memory.

In any case, the unequal sizes makes the allocation a bit more dificult to follow.

In your case you have plenty allocated, lsps -s states only 5% in use.

The next possible cause is that the private segment is full.

svmon -C command should help us there. Need to look at segment with Eseg id #2, to see how much space the segment still has.

I would check your page space settings.

If your page space is nearly full (that is allocated, probably not written), you may have an application that has the environment variable PSALLOC set to "early".

So, please verify your paging space settings and size.

As you didnt mention your version of AIX you will need to use either vmtune, or vmo to see the current settings, and lsls -s and lsps -a to display current usage statistics.

Hope this helps.
