Previously the bootstrap check for max number of threads was increased from 2048 to 4096 yet the docs were never adjusted for this change. This commit addresses this so the docs are in-line with the limit enforced in the bootstrap check. Relates #27511

=== Number of threads
|
|
|
|
Elasticsearch uses a number of thread pools for different types of operations.
|
|
It is important that it is able to create new threads whenever needed. Make
|
|
sure that the number of threads that the Elasticsearch user can create is at
|
|
least 4096.
|
|
|
|
This can be done by setting <<ulimit,`ulimit -u 4096`>> as root before
|
|
starting Elasticsearch, or by setting `nproc` to `4096` in
|
|
<<limits.conf,`/etc/security/limits.conf`>>.
