Kibana 6.5.0 Javascript heap out of memory

[drjackal (Jack Lauret)]

Hi all,

I have installed Kibana 6.5.0 to replace 6.4.0 on my Windows box.
After starting Kibana now says
Optimizing and caching bundles for ml, stateSessionStorageRedirect, status_page, timelion, graph, monitoring, space_selector, login, logout, dashboardViewer, apm, canvas, infra and kibana. This may take a few minutes.

This takes a while and then Kibana quits with the following error:

<--- Last few GCs --->

I can imagine that I have to increase the java heap size. But how to do this on my Windows box?

Any help is highly appreciated.

hi @drjackal,

actually, it's the nodejs heap you'd have to increase. you should not have to touch your JVM.

you can pass in the NODE_OPTIONS when starting kibana.

see https://github.com/elastic/kibana/issues/1924#issuecomment-399376071 for details.

Restarting Kibana sometimes does the trick to, YMMV.

Well, @thomasneirynck, that did the job.

I started node.exe manually with --max_old_space_size=4096 and Kibana started and optimized the bundles. (node.exe" --max_old_space_size=4096 --no-warnings "D:\ELK-Stack\kibana-6.5.0\src\cli")
Now I can start kibana without add --max_old_space_size=4096.

Thank you!
