[jira] [Updated] (CAMEL-9195) Memory leak in UndertowProducer
[ https://issues.apache.org/jira/browse/CAMEL-9195?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Claus Ibsen updated CAMEL-9195:
-------------------------------
Fix Version/s: 2.16.1
2.17.0
> Memory leak in UndertowProducer
> -------------------------------
>
> Key: CAMEL-9195
> URL: https://issues.apache.org/jira/browse/CAMEL-9195
> Project: Camel
> Issue Type: Bug
> Components: camel-undertow
> Affects Versions: 2.16.0
> Reporter: James Netherton
> Fix For: 2.17.0, 2.16.1
>
>
> The UndertowProducer class leaks memory over time due to the repeated creation of ByteBufferSlicePool for each HTTP client request. My understanding of this class is that instances of it should be limited and cached if possible.
> Here's an example RouteBuilder to replicate the issue. In a short time it will result in an OutOfMemoryError.
> {code}
> public class UndertowRouteBuilder extends RouteBuilder {
> @Override
> public void configure() throws Exception {
> from("undertow:http://localhost:8080/test").to("log:undertow?showAll=true");
> from("timer:foo?period=5000").transform(constant("hello world")).to("undertow:http://localhost:8080/test");
> }
> }
> {code}
