pjack created TS-3433:
-------------------------
Summary: Use extra memory than expected
Key: TS-3433
URL: https://issues.apache.org/jira/browse/TS-3433
Project: Traffic Server
Issue Type: Bug
Components: Cache
Reporter: pjack
the storage size is 16G, and ram_cache.size use the default value : (-1)
I expect the memory of the process should be less than 200MB, but it used 1.5G
and more until my server out of memory.
I checked the ram_cache size and I found bytes_used > total_bytes.
OS: Ubuntu 12.04 with 3.13.0-32 kernal
traffic server version: 4.2.3
$curl http://localhost:8080/_status | grep ram
"proxy.process.cache.ram_cache.total_bytes": "13410304",
"proxy.process.cache.ram_cache.bytes_used": "133754880",
"proxy.process.cache.ram_cache.hits": "12322",
"proxy.process.cache.ram_cache.misses": "55584",
But if I setup the ram_cache.size to a fixed value, then the bytes_used will be
always smaller than total_bytes. Please let me know if it is a correct scenario
or some kind of bug?
Thanks!
