unable to restart fess

(from github.com/wumpz)
I need some kind of starter. I am using the latest docker image with elasticsearch included. At the moment there is no configuration change except a web crawler.

Fess indexed successfully. Something about 60000 Docs, Index size 600MB.

Now I am not able to restart fess due to

ElasticSearch does not start anymore. Fess is restarting itself again and again to find a running elasticsearch.

I can’t see any exception warning or stuff. Where should I look for hints?

Did you check the console log printed by docker?
I think elasticsearch failed to start.

Do you mean this:

And after checking for elasticsearch til #60, it restarts fess again.

Does your server have enough memory?
OOM Killer might kill the process.

(from github.com/wumpz)
I started the docker container without any memory limitations. Therefore the standard configuration should be in place. By the way, this server runs with 20GB ram.

However, shouldn’t there be some kind of error message if the process is killed?

(from github.com/marevol)
What command did you run?

(from github.com/wumpz)
It is part of a docker compose file. I did not apply a command here. Therefore the one in your image applies. Right?

(from github.com/wumpz)
This is the part of my docker-compose file, that starts fess.

fessserver:
image: codelibs/fess:latest
restart: always
volumes:
- fess_config:/opt/fess
- elasticsearch_config:/etc/elasticsearch
- elasticsearch_data:/var/lib/elasticsearch
ports:
- “8083:8080”

(from github.com/marevol)

  • elasticsearch_config:/etc/elasticsearch

It’s better to check configuration files in the above.

(from github.com/wumpz)
I attached the three files within this directory. I skipped the keystore file.

fess_es_config.zip

Since I did not change anything, except over FESS web gui, I assume this is the standard configuration.

(from github.com/wumpz)
So where can I look next for some problems?

(from github.com/marevol)
Did you check /var/log/messages or syslog in the host?

(from github.com/wumpz)
Found a hs_err - file.

hs_err_pid84.zip

Could this something Java 11 problematic using elasticsearch be:

Reverted back to version 12.6.1, rebuilt the complete index.

Now fess restarts without any problems.

Curiously at the same directory fess finds nearly 5000 documents less.

(from github.com/wumpz)
So the older version runs without any problems. I stick with it. Thx for your help.
