Send gc log and force dump if you can when it happens.

Unfortunately, I have only this much information with me. However following
is my speficiations, if they are any helpful :-

/usr/bin/java -d64 -Xms5000M -Xmx5000M -XX:+UseParallelGC -verbose:gc
-XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xloggc:$GC_LOGFILE
-XX:+CMSPermGenSweepingEnabled -Dsolr.solr.home=multicore
 -Denable.slave=true -jar start.jar

32GiB RAM


Any thoughts? Will a switch to ConcurrentGC help in any means?

AFAIK, solr 1.4 is on Lucene 2.9.1 so this patch is already applied to
the version you are using.
maybe you can provide the stacktrace and more deatails about your
problem and report back?
