I just downloaded solr 4.8.0 from the apache website to my ubuntu 12.04, 64 Bit, 3GB ram VPS server and extracted it. Then I installed the openjdk-7-jre using this command:

sudo apt-get install openjdk-7-jre

when I tried to start solr using the example start.jar (/solr/example/start.jar) using

java -jar start.jar

I get much output in the console but after about 15 seconds the process exits with these last lines:

2941 [coreLoadExecutor-4-thread-1] INFO  org.apache.solr.core.CoreContainer  ? registering core: collection1

Killed
root@myawsmhostname:/usr/local/solr/example#

It just says Killed in the last line but I didn't do anything and I didn't touch the keyboard while it was running.

Btw: I am able to access the web-ui at port 8983. I can even browse that ui but after 15-30 seconds -- baam the process gets killed ._________.

Does anyone know that issue or know a workaroung?

I have searched all over the net but couldn't find a solution, that's why I assume that it's not an solr or jetty error, more a Java or Ubuntu thing.

Check the java memory settings on the java command line that starts your app. For example, you use -Xms for minimum heap size, -Xmx for max heap size, and -XX:MaxPermSize for the "permanent generation" heap (a different memory pool). Reasonable values if you are running nothing else on this 3GB server:

-Xms1024m -Xmx2048m -XX:MaxPermSize=256m

Without knowing more about your app and java memory tuning, you'll find this to be a trial and error process. You can probably increase -Xmx a bit without running out of memory.

  • Still gets killed. App is Solrs standart start.jar. Java memory tuning? Everything default, fresh install of the opendjdk jre. syslog file says nothing about java, messages too. Is there any Java-specific log file on the system? – user3593022 May 03 '14 at 14:39
  • sorry for slow response, but for the record, there is not likely to be a system-wide java log file. There may be something from solr itself, but it's more likely to be the system OOM-killer that you need to find log info from. check the output of `dmesg` for info from the OOM-killer, and try to adjust the java memory sizes a bit downward to see if that helps. Also, note that I had a typo: `-Xmx2048` should be `-Xmx2048m`. I've corrected the answer. – Dan Pritts Jun 16 '14 at 14:11
