Regression from SpringBoot 3.2.2 Factory method 'webClientHttpConnector' threw exception with message: Cannot reserve 49152 bytes of direct buffer memory (allocated: 10452747, limit: 10485760)
KafkaProServerless opened this issue · comments
Hello team,
I would like to reach out with a small issue.
This issue, is only observed when using SpringBoot 3.2.2. We changed to SpringBoot 3.2.1 and SpringBoot 3.2.0, same setup, no issue.
With SpringBoot 3.2.2, at application startup, we are observing this issue:
Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

This is regardless of how much memory we give to the application (We went all the way to give 40G of mem to this container which used to use 256MB).
The image has been built with GraalVM, running on docker
What are the ways needed to resolve this issue?
@KafkaProServerless Please provide a reproducible example.
Thank you @violetagg for the answer.
The project is quite big.
While I am removing things, may I ask if there are anything I can try to pin down the issue?
Change some memory limit? Enable debug log? remove some dependencies?
@KafkaProServerless Your project uses a lot of third party libraries because of this we need a reproducible example. From Reactor Netty point of view there is nothing that comes to my mind as a change that can cause this - https://github.com/reactor/reactor-netty/releases/tag/v1.1.15
May be try to change the used Reactor BOM - instead of 2023.0.2, try 2023.0.1

Hey @violetagg ,
Again, thank you for looking into this.
Our team is working on this issue, and we believe to have more clues.
With below code, issue is reproducible 100%
@Bean
public WebClient getWebClient(final WebClient.Builder builder, final SslContext sslContext) {
final var clientHttpConnector = new ReactorClientHttpConnector(HttpClient.create().wiretap(true).metrics(true, Function.identity()).protocol(HttpProtocol.HTTP11).secure(sslContextSpec -> sslContextSpec.sslContext(sslContext).handshakeTimeout(Duration.ofMinutes(1L)).closeNotifyFlushTimeout(Duration.ofMinutes(1L)).closeNotifyReadTimeout(Duration.ofMinutes(1L))));
return builder.baseUrl(hostAndPort).defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE).clientConnector(clientHttpConnector).build();
}
While strangely, with this code, it is working!
@Bean
public WebClient getWebClient(final SslContext sslContext) {
final var clientHttpConnector = new ReactorClientHttpConnector(HttpClient.create().wiretap(true).metrics(true, Function.identity()).protocol(HttpProtocol.HTTP11).secure(sslContextSpec -> sslContextSpec.sslContext(sslContext).handshakeTimeout(Duration.ofMinutes(1L)).closeNotifyFlushTimeout(Duration.ofMinutes(1L)).closeNotifyReadTimeout(Duration.ofMinutes(1L))));
return WebClient.builder().baseUrl(hostAndPort).defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE).clientConnector(clientHttpConnector).build();
}
Therefore, I think there is an issue with this final WebClient.Builder builder
It seems to correlate with log:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.reactive.function.client.WebClient$Builder]: Factory method 'webClientBuilder' threw exception with message: Error creating bean with name 'webClientHttpConnectorCustomizer' defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/function/client/ClientHttpConnectorAutoConfiguration.class]: Unsatisfied dependency expressed through method 'webClientHttpConnectorCustomizer' parameter 0: Error creating bean with name 'webClientHttpConnector' defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/function/client/ClientHttpConnectorAutoConfiguration.class]: Failed to instantiate [org.springframework.http.client.reactive.ClientHttpConnector]: Factory method 'webClientHttpConnector' threw exception with message: Cannot reserve 49152 bytes of direct buffer memory (allocated: 10452747, limit: 10485760)
May I ask if you know if there can be any regression caused by final WebClient.Builder builder?
May I ask if you know if there can be any regression caused by final WebClient.Builder builder?
Please contact Spring Framework maintainers
Understood, thank you
