Jason Mathison commented on HTTPCORE-782:
-----------------------------------------
Turning this on globally would be very expensive for us. Would it be enough to
capture this tracing while an issue is in progress, or is it important that you
get the logging from when the issue first starts?

> Key: HTTPCORE-782
> URL: https://issues.apache.org/jira/browse/HTTPCORE-782
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore
> Affects Versions: 5.3.4
> Reporter: Jason Mathison
> Priority: Blocker
> Attachments: Thread Stack Traces
>
>
> We have a service that is occasionally having a thread get stuck in a state
> where it consumes as much CPU as possible. The thread will create and release
> a huge number of objects without causing an overall memory leak.
> We gathered a series of stack traces from this happening on one of our
> production instances that indicates that the thread is stuck inside of the
> "while (inEncryptedBuf.hasRemaining()) { " in
> org.apache.hc.core5.reactor.ssl.SSLIOSession.decryptData(SSLIOSession.java)
> This issue has been happening a couple of times a week for several weeks. We
> believe that it is always happening against a specific endpoint and are
> attempting to gather more information about what this endpoint is doing.
> This issue started happening a few weeks ago when we were on a slightly older
> version of this library. We happened to update to the latest version of these
> libraries and this is continuing to happen. We have had no success in causing
> this issue to happen in our testing environments where we could gather a heap
> dump.
