Hi,
Around 50threads/sec the request bring back " No read Solr server
available" , the gc seems to be quite full, but I didn"t get OOM error,
would love an advice.
Thanks a lot
Details :
8G of memory
4CPU : Intel(R) Xeon(R) CPU 5160 @ 3.00GHz
Solr 1.3
# Arguments to pass to the Java virtual machine (JVM).
JAVA_OPTS="-Xms1000m -Xmx4000m -XX:+UseParallelGC
-XX:+HeapDumpOnOutOfMemoryError -Xloggc:gc.log -XX:+PrintGCDetails
-XX:+PrintGCTimeStamps"
5.3G of data with 8,2M of documents.
Thanks a lot for the help
