Recovering from Insufficient Memory Errors

To recover from insufficient memory errors, do the following:

• Wait, and try again later.

  The system automatically reallocates memory when processes finish running. Many processes are not visible to users, and start and stop without any indication. When the processes stop, you may have sufficient memory available. Run your command or process again.

• Locate and remove unnecessary processes.
  1. Run the ps -ef command to list the processes currently running.
  2. Locate any unnecessary processes, and run the kill ProcessIDNumber command to remove them. If you do not own the process, you need to run the su command to change to the root user, who owns all processes, or to the user who owns the process, and run the kill command again.
  3. Run your command or process again. If you still do not have sufficient memory, repeat this procedure.
• Add more paging space with the System Manager Interface Tool (SMIT) utility. (Use the Physical and Logical Storage option in the Main Menu.)
• Add more physical memory.
