Swing application freeze

Rédigé par gorki Aucun commentaire

Problème :

J'ai une application en client lourd java qui fonctionnait bien. Depuis quelques jours, elle freeze quand j'ouvre une série de popup ce qu'elle ne faisait pas avant (ou que je n'avais pas remarqué)

Solution :

J'ai désactivé les agents que j'avais en même temps, supprimer les options inutiles de la JVM, toujours rien.

La stacktrace me dit ceci :

Logitech Media Server and Synology DS218play

Rédigé par gorki Aucun commentaire

Problem :

Logitech media server is not supported anymore by Synology (bouuuuh.)

Spotted by number of threads :

  • https://community.synology.com/enu/forum/1/post/141628
  • https://www.avforums.com/threads/synology-and-lms.2332981/

I have a DS218play, ARMv8 based

Solution :

Instead of switching back to the old package, or create my new one, I decided to install docker.

I followed this thread : https://stackoverflow.com/questions/52520008/can-i-install-docker-on-arm8-based-synology-nas

Quite easy.

I follow also the script here : https://raw.githubusercontent.com/wdmomoxx/catdriver/master/install-docker.sh but I download docker from original site instead.

I use this image : https://registry.hub.docker.com/r/lmscommunity/logitechmediaserver/#!

And run this command, not perfect (log, daemon, docker image should be started... will update this later).

#!/bin/bash

docker run --network=host -it \
      -v "/volume1/partage/docker/lms/config":"/config":rw \
	  -v "/volume1/music":"/music":ro \
	  -v "/volume1/partage/docker/lms/playlist":"/playlist":rw \
	  -v "/etc/localtime":"/etc/localtime":ro \
	  -v "/etc/TZ":"/etc/timezone":ro \
	  -v "/dev":"/dev" \
       lmscommunity/logitechmediaserver &> /volume1/partage/docker/lms-docker.log

Added :  --network=host  (and remove mapping port) and -v "/dev":"/dev"
