When I first installed it using apt-get everything went smoothly and I was able to start it as a service and verified it was working by using curl: Later I noticed that it was using a lot of memory (2GB), so I stopped the service, and thereafter I haven't been able to restart it. Tried 7.13.4 and 7.13.2 (which is working perfectly on my Ubuntu 20.10 vm). I changed the log level to 'all' in the log4j config, but can't find anything out of the ordinary. The **sun.misc.Unsafe unavailable** exception exists even on the installation that works well. Can anyone help to diagnose this issue?

Bah! Seems like a Ubuntu issue with systemd timing out: > **[How to prevent systemd service start operation from timing out](https://sleeplessbeastie.eu/2020/02/29/how-to-prevent-systemd-service-start-operation-from-timing-out/)** > > Specify systemd startup timeout option to prevent service start operation from timing out. ---

At first Elasticsearch worked very fine on my local development system, when developing the search of my [Site](https://www.nmmapper.com). I stopped Elasticsearch because the rest of the work didn't need it. But now am working on a new project that requires Elasticsearch but it's not starting. My main development system is Debian 10 fully updated and patched. But when I issue systemctl start elasticsearch I get this Job for elasticsearch.s… ---
