Hi. I'm using ES 2.3.2 with jdk1.8.0_60 and CMS gc. (
Heap keeps growing during several days, All I can do is just rolling restarting nodes. I hope someone help me.
I'm wondering why heap is not freed after full gc
SegmentCoreReader is the biggest part of heap, but this memory is occupied right after ES started. So, this memory does increase relatively small. (I checked it via
segments in node stats)
HashMap is used for query cache and request cache, so this is a fixed area. (I've configured 5% of heap for query cache and request cache)
indices.queries.cache.size: 5% indices.requests.cache.size: 5%
Could someone explain what does
Reminder which uses 5.1GB means?
