I am running into a similar issue with Lucene 3.6 which I believe is used in Solr 3.4.
Following is the exception stack trace: 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) Exception in thread "Load thread" java.lang.OutOfMemoryError: classblock allocation, 2814576 loaded, 2816K footprint, in check_alloc (src/jvm/model/classload/classalloc.c:215). Attempting to allocate 4320M bytes There is insufficient native memory for the Java Runtime Environment to continue. Possible reasons: The system is out of physical RAM or swap space In 32 bit mode, the process size limit was hit Possible solutions: Reduce memory load on the system Increase physical memory or swap space Check if swap backing store is full Use 64 bit Java on a 64 bit OS Decrease Java heap size (-Xmx/-Xms) Decrease number of Java threads Decrease Java thread stack sizes (-Xss) Disable compressed references (-XXcompressedRefs=false) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.lang.ClassLoader.defineClass1(Native Method) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.spi.ThrowableInformation.getThrowableStrRep(ThrowableInformation.java:87) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.spi.LoggingEvent.getThrowableStrRep(LoggingEvent.java:413) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.WriterAppender.subAppend(WriterAppender.java:313) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.RollingFileAppender.subAppend(RollingFileAppender.java:276) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.WriterAppender.append(WriterAppender.java:162) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.AppenderSkeleton.doAppend(AppenderSkeleton.java:251) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.helpers.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:66) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.Category.callAppenders(Category.java:206) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.Category.forcedLog(Category.java:391) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at org.apache.log4j.Category.warn(Category.java:1060) 2012-09-08 18:08:56,341 WARN [STDERR] (Load thread:) at com.teneo.esa.common.util.Logger.printStack(Logger.java:584) JVM details: Jrockit R28.2.3, Xms4320m, Xmx4320m.
