java.lang.OutOfMemoryError: Map failed

Tue, 02 Apr 2013 01:24:59 -0700 

Hi

Recently solr crashed. I've found this in the error log.
My commit settings are loking like this:
     <autoCommit>
       <maxTime>10000</maxTime>
       <openSearcher>false</openSearcher>
     </autoCommit>

       <autoSoftCommit>
         <maxTime>2000</maxTime>
       </autoSoftCommit>

The machine has 10GB of memory. Tomcat is running with -Xms2048m -Xmx6144m

Versions
Solr: 4.2
Tomcat: 7.0.33
Java: 1.7

Anybody any idea?

Thx!

Arkadi
