Re: Stopping Solr JVM on OOM

In order to force a OOM do this: - index a sizable amount of docs with normal -Xmx, if you already have 350k docs indexed, that should be enough - now, stop solr and decrease memory, like -Xmx=15m, start it, and run a query with a facet on a field with very high cardinality, ask for all facets.

Re: Stopping Solr JVM on OOM

I set the heap to 16 mb and tried to index about 350k records using a DIH. This did throw an OOM for that particular thread in the console, but the oom script wasn't called and solr was running properly. Moreover, solr also managed to index all 350k records. Is this the correct way to o about

Re: Stopping Solr JVM on OOM

Hello Shawn, I made the necessary changes to that oom script? How does it look now? Also can you suggest some way of testing it with solr? How do I make solr oom on purpose? Thanks On Wed, 9 Mar 2016, 19:11 Shawn Heisey, wrote: > On 3/9/2016 6:07 AM, Binoy Dalal wrote: > >

Hi Shawn, The JIRA issue is SOLR-8803 (https://issues.apache.org/jira/browse/SOLR-8803 ). I've used "git diff" and created a patch but it only has the changes that I made to the solr.cmd file under bin to add the -XX:OnOutOfMemoryError option. There's the entire file of the actual OOM kill script

Hi Shawn, I've just finished writing a batch oom killer script and it seems to work fine. I couldn't try it on the actual solr process since I'm a bit stumped on how I can make solr throw an oom at will. Although I did write another code that does throw an oom upon which this script is called and

Re: Stopping Solr JVM on OOM

You can use ping functionality by setting time-out that suits for your container/web-apps. If its not working then you can restart your container. Cheers! If any other solution I am interested too. On Fri, Feb 26, 2016 at 2:19 AM, CP Mishra wrote: > Solr & Lucene dev folks

Solr & Lucene dev folks must be catching Throwable for a reason. Anyway, I am asking for solutions that I can use. On Thu, Feb 25, 2016 at 3:06 PM, Fuad Efendi wrote: > The best practice: do not ever try to catch Throwable or its descendants > Error, VirtualMachineError,

Re: Stopping Solr JVM on OOM

The best practice: do not ever try to catch Throwable or its descendants Error, VirtualMachineError, OutOfMemoryError, and etc.  Never ever. Also, do not swallow InterruptedException in a loop. Few simple rules to avoid hanging application. If we follow these, there will be no question "what

Stopping Solr JVM on OOM

Looking at the previous threads (and in our tests), oom script specified at command line does not work as OOM exception is trapped and converted to RuntimeException. So, what is the best way to stop Solr when it gets in OOM state? The only way I see is to override multiple handlers and do
