SAP B1 HANA stops unexpectedly

Hi all,

We have a customer with B1 HANA system, and we are experiencing the following problem: without notice, the HANA database stops always at 13:30, after running 2 or 3 continuous days.

We searched for any cron jobs but found none. We are new with HANA and can't figure out the reason for this problem.

Based on the HANA logs, we found that a SIGQUIT event is always triggered when this problem occurs. This event is linked to user ndbadm (user id 1001) and the process that triggers is hdbnameserver (pid 31947), and can't figure out the source of this behavior...

Here are the "daemon_xxxx.trc" log file:

Any ideas that can justify this HANA db shutdown?

Thanks
