-----------------------------
> 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
> Affects Versions: 5.2.0
> Reporter: Sudheer Vinukonda
> Assignee: Sudheer Vinukonda
> Priority: Blocker
> Fix For: 5.2.0
>
>
> 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)
> {code}
