The example use springboot 3.0 is normal, but use springboot 3.3 have exception. Maybe it is different from #31902

        HttpHeaders headers = new HttpHeaders();
        Enumeration<String> headerNames = request.getHeaderNames();
        //set head from request 
        HttpEntity httpEntity = new HttpEntity<>(body, headers);
        ClientHttpRequestFactory clientHttpRequestFactory = (new SimpleClientHttpRequestFactory() {
             //... 
        });

        ClientHttpRequestFactory factory = new BufferingClientHttpRequestFactory(clientHttpRequestFactory); // already use BufferingClientHttpRequestFactory

        RestTemplate restTemplate = new RestTemplate(factory);
        ResponseEntity serverResponse = null;

        serverResponse = restTemplate.exchange(uri, method, httpEntity, String.class); //this line have ResourceAccessException : insufficient data written

        // ... other
    } catch (Exception e) {
        logger.error("", e);

@rajukosna we never got the sample we requested. If you can reproduce the problem with a minimal sample application (something we can git clone or unzip) please create a new issue here: https://github.com/spring-projects/spring-framework/issues

Note: if you cannot reproduce the problem with a minimal sample application this is likely to be a problem specific to your application. In this case please ask a question on StackOverflow.

@bclozel Example code:

ResponseEntity<ResponseDTO> responseEntity = null;
        try {
            LOGGER.info(REST_CALL_FOR_URL);
            if (headers == null) {
                headers = new HttpHeaders();
            }
            headers.add(HEADER_NAME, getFullContextInJson());

            HttpEntity<?> httpEntity = new HttpEntity<>(body, headers);
            responseEntity = restTemplate.exchange(UriComponentsBuilder.fromHttpUrl(url).build(true).toUriString(), 
                    httpMethod, httpEntity, ResponseDTO.class);

            return responseEntity;
        } catch (RestClientException restClientException) {
            logger(restClientException);
            return new ResponseEntity<>(restClientException.getMessage(), HttpStatus.BAD_REQUEST);
        }

@rajukosna We need a complete sample application to be able to help you. That way we know exactly what library versions you're using and how your application is configured. You should also upgrade to 3.3.7 or 3.4.1
