Elasticsearch indexing error: [parent] Data too large, data for [<http_request>] would be [123647988/117.9mb]


Well-known member

for first time I am trying out ES right now. I got it installed on my localhost to try it out on a safe environment first.

I got this error while rebuilding the search index. It seems some kind of limit stopped the rebuilding. I just don't know what limit is exceeded.
Does anyone know what I have to increase so it works for indexing?
There is also a mention of an addon here, but I believe it is not the cause of that.



XF: 2.1.3
XFES. 2.1.2
ES: 7.4.2
MariaDB: 10.1.32

That didn't help. But I found out the solution. I just had to increase the limit for ES to


I thought I did that before I posted here but it turns out I forgot to save it in the file, so it had no effect. Stupid me, sorry.
