-------------------------------------
Summary: possible memory leak in v5.2.0
Key: TS-3257
URL: https://issues.apache.org/jira/browse/TS-3257
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Sudheer Vinukonda
After running v5.2.0 over the weekend on one of our prod hosts, I've noticed
that the RES memory from top grew to 21g (the corresponding RES memory on a
v5.0 prod host is 10g). Looking at the memory dump, it seems that it might be
leaking 4K iobuffers. The memory dump shows as much as 10g of 4K buffers
allocated/in-use (on the corresponding v5 host, the 4k buffers are only at
300MB level)

-bash-4.1$ sudo grep "memory/ioBufAllocator\[5\]" traffic.out
