=== Known issues
|
|
* When upgrading clusters from version 8.11.4 or earlier, if your cluster contains non-master-eligible nodes,
|
|
information about the new functionality of these upgraded nodes may not be registered properly with the master node.
|
|
This can lead to some new functionality added since 8.12.0 not being accessible on the upgraded cluster.
|
|
If your cluster is running on ECK 2.12.1 and above, this may cause problems with finalizing the upgrade.
|
|
To resolve this issue, perform a rolling restart on the non-master-eligible nodes once all Elasticsearch nodes
|
|
are upgraded. This issue is fixed in 8.15.0.
|
|
|
|
* The `pytorch_inference` process used to run Machine Learning models can consume large amounts of memory.
|
|
In environments where the available memory is limited, the OS Out of Memory Killer will kill the `pytorch_inference`
|
|
process to reclaim memory. This can cause inference requests to fail.
|
|
Elasticsearch will automatically restart the `pytorch_inference` process
|
|
after it is killed up to four times in 24 hours. (issue: {es-issue}110530[#110530])

|
|
|
* Searches involving nodes upgraded to 8.13.0 and a coordinator node that is running on version
|
|
8.12 or earlier can produce duplicate buckets when running `date_histogram` or `histogram`
|
|
aggregations. This can happen during a rolling upgrade to 8.13 or while running cross-cluster
|
|
searches. (issue: {es-issue}108181[#108181]).
