New instance on 7.7.06.09 crashes with SIGNAL 11 (SIGSEGV)

After having lots of trouble to migrate our 7.6 instance to 7.7, we have decided to create a new instance on 7.7 and migrating all tables with our own dbcopy tool.

The new instance is configured the same way like our old 7.6 instance. We have started the instance and copied all data to it. After that we have started our Java based appserver with the new instance but the instance crashes quite soon. We have now switched back to the 7.6 instance which is one the same server and works fine.

I have put the tarball of the DIAGHISTORY directory here:

[DIAGHISTORY|http://www.invoca.ch/pub/maxdb/DIAGHISTORY.tar.bz2]

Any ideas how to find out what's wrong?

Regards,

Simon

    Hello Simon,

    can you tell us linux version you are using with:

    uname -a

    rpm -q -a grep glibc-2

    Regards

      Hi Natalia,

      Thanks for all your help and the link to PTS which fixed our segfaults.

      We have finally migrated the production instance using our Java db migrator to version 7.7 and all seems to work well.

      Regards,

      Simon

    Hello Simon,

    1)

    first of all the atached files you have posted are very difficult to read , try it yourself. So I would suggest to convert them to ASCII files (from xml) with protconv tool (sapdb/programs/bin)

    -> reproduce the crash , so fresh new crash is in the knlmsg (/sapdb/data/wrk/<SID>)

    ->switch to this directory

    -> run

    protconv -o knldiag.txt

    2)

    try to set shared UseSharedSQL to NO and reproduce the try if it is still crashing

    Regards

    Ivan
