Error description

  • The alt_disk_install (and other file system related
    commands) may fail with "File table overflow"
    errors.  The errors continue until the system
    is rebooted or the inode cache is increased:
    ...
    Creating /alt_inst/var file system.
    mount: /dev/alt_hd2 on /alt_inst/usr: File table overflow
    0505-121 alt_disk_install: Error.
    Cleaning up.
    Could not load program grep:
            Dependent module /usr/lib/libc.a(shr.o)
     could not be loaded.
    Could not load module /usr/lib/libc.a(shr.o).
    System error: File table overflow
    
    This problem may also just cause the system to slow
    down, with perfpmr showing the iAlloc kernel function
    is taking a lot of CPU time.
    

Local fix

  • Increase the size of the inode cache
    using the ioo command (j2_inodeCacheSize
    option).
