Yep, as mentioned here, I can share it.
@Ignacio_Vera: is it safe to post the file as gist? The file has 73MB and as far as I can see, the only "private data" is the hostname. Anything I should consider? As its our company ES, I would not like to share any confidential data.

We just uncover a bug on the enrich cache introduced in 8.16 where the cache will slowly grow until it exhaust the JVM heap. If you are using enrich and facing OOM, the way to avoid it is to set the setting enrich.cache_size back to the previous value of 1000.
