java.lang.OutOfMemoryError, VM may need to be forcibly terminated

[Oleg Burlaca <ol...@burlaca.com>]

Hello,

I've searched the list for this kind of error but never find one that is
similar to my case:

     Java HotSpot(TM) Client VM warning:
     Exception java.lang.OutOfMemoryError occurred dispatching signal
     SIGTERM to handler- the VM may need to be forcibly terminated


I use the latest stable SOLR 1.4 and start it with Jetty from the 
/example/ folder.

Sometimes SOLR dies without writing to the stderrout.log
(I use the script from http://wiki.apache.org/solr/SolrJetty)

The messages above appears in the standard error stream instead of the 
log file. (i.e. it appears directly in the SSH window).

I've set:
       <New class="org.mortbay.thread.BoundedThreadPool">
         <Set name="minThreads">2</Set>
         <Set name="lowThreads">2</Set>
         <Set name="maxThreads">2</Set>
       </New>

Is there a way to solve this? SOLR is on a VPS with 512MB of RAM.

Regards,
Oleg Burlaca

Hi -

The best way is probably to add more ram. :-)

That error apparently results from running out of perm gen space, and with
512m, you may not have much perm gen space.

Options for increasing this can be found
http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp

But, if you don't have enough memory, that's just going to move the problem.

You can watch memory usage with jconsole, or get more detail with something
like yourkit.
