Subject Memory Leak in solr 4.8.1
Date Wed, 08 Apr 2015 21:00:58 GMT
I have a solr cloud instance with 8 nodes, 4 shards and facing memory leak on
the JVMs

here are the details of the instance.

1. 8 nodes, 4 shards(2 nodes per shard)
2. each node having about 55 GB of Data, in total there is 450 million
documents in the collection. so the document size is not huge, 
3. The schema has 42 fields, it gets reloaded every 15 mins with about
50,000 documents. Now we have primary Key for the index, so when there are
any duplicates the document gets re-written.
4. The GC policy is CMS, with heap size min and max = 8 gb and perm size =
512 mb and RAM on the VM is 24 gb.

when users start searching in solr and not always but often the heap keeps
growing and the GC cycles are not clearing up the heap. I see GC running for
almost 100,000 ms with still not clearing up the heap.

Appreciate any advice on this.
