Dear all,
I need your help and how to solve my problem.
platform: sybase ase 15.0.3 ebf#4, red hat.
application: power builder 6.

I am implementing semantic partition, but find problems in database log.
After we restart db server, the error's gone, until 3 days appear again.

I got error message every 3 days after restart database server. Address always has this value (0x0x000000000191491e). User get message 'ASE terminating this process' for particular session.

Please help me, and what should we do.
Thanks in advance.

There should be more stacktrace info on this which has the function calls. Please post that also from the errorlog.

Also, if you have a support account, you should raise a case with Sybase.
