    Question Unanswered: hpkaiodelseg: ASYNC_DELSEG failed error message ?

    I just enabled KAIO on my a HP-UX B.11.11 U 9000/800 server running Informix 9.30 and am seeing this error message :

    16:15:02 Attempting to free unused operating system segments. This
    operation may take several minutes.

    16:15:02 Freed 1 shared memory segment(s) (524288000 bytes)

    Has anyone seen this before ? It looks like it failed to delete a segment (I'm assuming its a memory segment) but somehow succeeded later.

    Any advice would be much appreciated

    Hi,
    Please test if the Minor and Mayor number of i/o /dev/async is correct.
    Also, test if aplicate all patches of HP for Ibm:Informix.

    Hi,

    A question if you unset of KAIOON, the on-line raises?

    No, I don't think the error will happen when KAIOON is disabled.

    We only turned on KAIO recently, and the error message was showing.

    I really wonder what error 22 means ..

    Hi,

    Ok,
    Please check this:
    Run getprivgrp, create file /etc/privgroup with line "informix MLOCK", next run setprivgrp -f /etc/privgrp.
    Next active KAIOON=1 and take On-Line to online.

    Gustavo.
