OOME error while importing 100M entries (online-import) causes the server to crash




      Trying to import 100M entries into DJ (used as a ID Store), the servers crashed after importing 98M entries with:

      head -60 hs_err_pid112970.log
      # There is insufficient memory for the Java Runtime Environment to continue.
      # Native memory allocation (mmap) failed to map 65536 bytes for committing reserved memory.
      # Possible reasons:
      #   The system is out of physical RAM or swap space
      #   In 32 bit mode, the process size limit was hit
      # Possible solutions:
      #   Reduce memory load on the system
      #   Increase physical memory or swap space
      #   Check if swap backing store is full
      #   Use 64 bit Java on a 64 bit OS
      #   Decrease Java heap size (-Xmx/-Xms)
      #   Decrease number of Java threads

      Note that:

      • We reproduced the problem several times, even after trying to increase heap size from 10GB to 20GB
      • There was more than enough memory on the host (80GB free) when the server crashes
      • We've run the exact same import with DJ2.6.3 without any problem (just after, on same host).
