Re: Out of Memory doing a query Solr 4.2

2013-03-15 Thread Bernd Fehling
We are currently using
Oracle Corporation Java HotSpot(TM) 64-Bit Server VM (1.7.0_07 23.3-b01)

Runs excellent and also no memory parameter tweaking neccessary.
Give enough physical and JVM memory, use -XX:+UseG1GC and thats it.

Also no saw tooth and GC timeouts from JVM as with earlier versions.

Regards
Bernd

 Why? Could this be the cause of the problem? This was working ok for Solr
 3.5.
 
 Could you recommend me one ?
 
 Thanks.

 Thank you for your help. I'm afraid it won't be so easy to change de jvm
 version, because it is required at the moment.

 It seems that Solr 4.2 supports Java 1.6 at least. Is that correct?

 Could you find any clue of what is happening in the attached traces? It
 would be great to know why it is happening now, because it was working for
 Solr 3.5.

Its probably not an OOM at all. instead its more likely IBM JVM is
probably miscompiling our code and producing large integers, like it
does quite often. For example, we had to disable testing it completely
recently for this reason. If someone were to report a JIRA issue that
mentioned IBM, I'd make the same comment there but in general not take
it seriously at all due to the kind of bugs i've seen from that JVM.

The fact that IBM JVM didnt miscompile 3.5's code is irrelevant.

 JVM: IBM J9 VM(1.6.0.2.4)

I don't recommend using this JVM.
