ASE 16 - signal 11 / stack trace - Snap::Validate() [KBA 3018138 ?]

[Mark_A_Parsons]

Trying to get ASE 16 up and running on a new Ubuntu host but generating a signal 11 stack trace during initial build/startup of the instance.

The stack trace looks (to me) like the same one mentioned in KBA 3018138:

- stack trace commences right after 'kernel bucket manager consolidator online'

- stack trace includes the same function calls, including Snap::Validate() and SnapValidation

- dataserver process hangs with the same final message in the errorlog 'The internal timer is not progressing. If this message is generated multiple times, report to SAP Technical Support and restart the server (alarminterval=0).'

I don't currently have access to the support/firewall so was curious if anyone might know the resolution to this issue?

Thanks,

Mark

Hi Mark,

The Simplified Native Access Plan is present in 16.0 and not on 15.7. Because of this, there's no need to use this trace flag in 15.7.
