    Unanswered: DB2 service is still going down

    Hi,

    as posted earlier, my DB2 service (Windows service) is going down when I start a more complex transaction on my WebAbb.

    Meantime I found out that there is a stack overflow, as I got the message:

    ADM0501C A stack overflow exception has occurred. The DB2 instance has
    terminated abnormally. To remedy this problem, you may increase the default
    stack size for db2syscs.exe using the db2hdr utility as follows: db2hdr
    \sqllib\bin\db2syscs.exe /s:<stackreserve>[,<stackcommit>] Note that increasing
    the default stack size will consume virtual memory space and may reduce the
    maximum number of concurrent connections. Contact IBM Support for further
    assistance.

    I've been looking for the db2hdr util, but I didn't find it.

    Has anyone any idea where to find this util or how to increase the stack size for db2syscs.exe?

    Thank you,

    Tux
