  • GreyNoise Quick IP Lookup Data Adapter can no longer be used with a free GreyNoise Community API tokens.

Shutdown of Graylog on OutOfMemoryError

Because of an error in HttpCore 4.4.12, which is required by Elasticsearch and older versions of Opensearch, OutOfMemoryError errors were not properly handled. The Reactor was stopped, which prevented proper Graylog operation and the reason (OutOfMemoryError) was not clearly visible. From now on, Graylog will shutdown on OutOfMemoryError, trying to log some basic information about the thread and memory consumption during this event.
