After restarting the Tableau Server, the Index and Search Server as well as the NLP, were in an error state. 

The following error can be found in the opensearch.log:

[2023-12-26T10:29:03,727][INFO ][o.o.b.BootstrapChecks    ] [g010t-vm-vhetst01]bound or publishing to a non-loopback address, enforcing bootstrap checks

[1] bootstrap checks failed
[1]: max virtual memory areas vm.max_map_count [131072] is too low, increase to at least [262144]



  • Tableau Server 2023.1.7
  • Red Hat (RHEL) Linux 8


Change the vm.max_map_count to the recommended size:
  • sysctl -w vm.max_map_count=262144
Or edit the /etc/sysctl.conf file for the permanent change. 


Virtual memory for the vm.max_map_count is not set high enough for starting the index/search server.  NLP failed to start due to it can't connect to Index and Search server.
