In reference to my prior thread: http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201403.mbox/%3ccac-cpvrzbhizomcdhkrhygqizguerntkwtkxwwx3j1rqcxe...@mail.gmail.com%3E
I followed the advice to set unmap=false on my indexes with promising results. Without performing any index updates I am seeing very stable memory usage and GC performance. However, I'm still sporadically seeing memory problems after replicating index updates. After performing another heap dump, I noticed that: java.lang.ref.Finalizer is occupying an inordinate amount of space. jmap reports it as an 'unreachable object', however GC was obviously not cleaning it up. I'm really not sure how to hunt down this problem, any help would be appreciated. -Harish
