Hello,
I'm investigating a memory leak in our java servers and I was wondering if you have similar issues.
Our configuration:
boxes with 64G of memory, 30G are allocated for echcache offheap cache, java - 8G, 1G - echcase in heap memory. Objects we cache in off heap memory are 40kb on average with max of 1 MB. 95 percentile - 100kb, 99 percentile - 250k. Also, we use SelfPopulatingCache.
We noticed that boxes are slowly leaking the memory, getting in GC hell state after 5-6 days. When I did memory dump I found:
Old gen was 6 GB
There were 13139 instances of class com.terracottatech.offheapstore.paging.Page and it holds first place in terms of number of instances.
My questions are:
is it normal to have so many live Page objects?
any known memory leaks?
what is the right way to approach it?
Thank you,
Alex
