the second time we had the error
java.lang.OutOfMemoryError: PermGen space
and solr stopped responding.
we use the default jetty installation with jdk1.6.0_21. after the last
time i tried to set the garbage collector "right"
these are my settings:
-D64 -server -Xms892m -Xmx2048m -XX:+UseConcMarkSweepGC
-XX:+UseParNewGC -XX:-HeapDumpOnOutOfMemoryError
-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled
as far as i thought, "-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled" should also cleanup the PermGen space.
what can we do?
ok, at the moment solr is not stopped and is running "all time". maybe
we should do a regular (daily) restart, then the problem should be
fixed. but how can we adjust the garbage settings, so that the PermGen
space is not running out of space...
