2946571 - Indexserver terminated simultaneously in different SAP HANA systems on the same host

Symptom

  • You have more than one SAP HANA system installed on the same host;
  • In the first system, you notice the indexserver of one of the SAP HANA systems was terminated abruptly:
    • In the indexserver trace file, you can't find a shutdown message, only the next startup message;
    • Upon checking the daemon trace file, you can see that the service was terminated with a similar message as follows:
       Process 'hdbindexserver', pid 156620 exited because it caught signal 9
  • In the second system, you notice an out of memory dump with "Allocation failure type: OPERATING_SYSTEM_LIMIT". In the oom trace file, you can see the Linux parameter /proc/sys/vm/max_map_count is set as recommended in SAP Note 1980196;
  • Both systems have no Global Allocation Limit set;
