This problem is most likely due to swap space being less. Ask your system administrator to increase the swap space. The rule of thumb is swap space should be twice that of physical memory. We faced this issue on AIX 5L box running Oracle Database 10gR2 10.2.0.1

Alternately you can run the HCVE script which is now part of RDA to do health check of database and confirm this.

1. Download RDA package for your OS from metalink.

2. Unzip the RDA package.

3. Go to the RDA directory and type below command to run. For an AIX system you will see options. Select your database version.

$ ./rda.sh -T hcve

Processing HCVE tests …
