Description

Can't get thread dumps when there are a lot of threads. There doesn't seem to be a way to change the ExchangeStrategies used in the InstanceWebProxy class to increase the buffer size...

Hi @v3rm0n

If you want to change the ExchangeStrategies to increase the buffer size used in the InstanceWebProxy, try to implement an InstanceWebClientCustomizer in your configuration.

It should look something like this:

@Bean
public InstanceWebClientCustomizer instanceWebClientCustomizer() {
	return new InstanceWebClientCustomizer() {
		@Override
		public void customize(InstanceWebClient.Builder instanceWebClientBuilder) {
			instanceWebClientBuilder.webClient(WebClient.builder()
				.exchangeStrategies(ExchangeStrategies
				.builder()
				.codecs(codecs -> codecs
					.defaultCodecs()
					.maxInMemorySize(500 * 1024))
				.build()));
		}
	};
}

You might also want to add a configuration like this one:

spring:
  codec:
    max-in-memory-size: 500KB

Please let us know if this helps you.

Regards
Uli

We tried this but this doesn't help, it looks like it does not change the correct buffer length (buffer was set to 1000KB)
With the changes applied we still get this stacktrace:
