    Unanswered: Informix hangs when try to add segment

    I have a problem with my IDS 9.30.FC2W8 on HP-UX 11.11
    on HPRP server (6 processors, 6GB RAM)
    Sometimes IDS hangs when it try to add new shared memory segment.
    In oline.log I have messages:
    HPUX KAIO Segment locked addr=0xa18f2000 size=32768000
    HPUX KAIO Segment locked addr=0xa18f2000 size=32768000
    HPUX KAIO Segment locked addr=0xa18f2000 size=32768000
    HPUX KAIO Segment locked addr=0xa18f2000 size=32768000
    HPUX KAIO Segment locked addr=0xa18f2000 size=32768000
    HPUX KAIO Segment locked addr=0xa18f2000 size=32768000
    and nothing more.
    after 5 minutes in online.log started information:
    VP Notify mechanism incomplete after 5 minutes. This can be due to slo
    w network file access. Will try 12 more times
    etc.
    onstat display online state but nothing work.
    onstat -g seg display only previous allocated segments not the last segment whitch it try to add.
    I have to kill oninit to restart IDS.

    My onconfig parameters:
    SHMBASE 0x0
    SHMVIRTSIZE 628000
    SHMADD 32000
    SHMTOTAL 0

    My HP-UX kernel parameters
    nfile: 60000
    semmni: 3000
    semmns: 3000
    semmnu: 1400
    shmmax: 4294967296
    shmmni: 500
    shmseg: 500

    Please help

    Hi,

    I suggest you that the parameter SHMADD=16384 and review the patchs of operating system.

    Gustavo.
