Hi,
I am using http client 4.3.2 and I have a few questions. 1) I am making lot of concurrent requests to a server. When creating requests, I want to debug and check which ports are newly created by the client. Currently, I can see the ports in netstat as pasted below. tcp4 0 0 172.16.11.138.7575 172.16.11.138.52014 ESTABLISHED I enabled the debug logging for MainClientExec class and it gives me the below information. Here it does not exactly tell me what is the source port that is being used for the connection. How can I use this ? Also, whenever MainClientExec prints the below line, does it mean a new connection is created with a new port or an existing port is being used ? 2014-02-14 13:01:01 DEBUG MainClientExec:217 - Opening connection {}->http://172.16.11.138:8983 2) My code looks like this for creating a http Client. I pass the client to SolrJ<https://cwiki.apache.org/confluence/display/solr/Using+SolrJ> which uses this client to make requests. SolrJ makes requests to a Solr server. HttpClientBuilder httpBuilder = HttpClientBuilder.create(); Builder socketConfig = SocketConfig.custom(); socketConfig.setSoReuseAddress(true); httpBuilder.setDefaultSocketConfig(socketConfig.build()); httpBuilder.setMaxConnTotal(100); httpBuilder.setMaxConnPerRoute(100); httpBuilder.disableRedirectHandling(); httpBuilder.useSystemProperties(); final CloseableHttpClient httpClient = httpBuilder.build(); This httpClient created above also throws some exceptions. Can I assume retry is successful and does this happen because I enabled socketReuseAddress ? 2014-02-14 12:53:21,415 - INFO [CloudSolrServer ThreadPool-1-thread-59:RetryExec@93] - I/O exception (java.net.SocketException) caught when processing request: Address already in use 2014-02-14 12:53:21,443 - INFO [CloudSolrServer ThreadPool-1-thread-59:RetryExec@106] - Retrying request 2014-02-14 12:53:47,299 - INFO [CloudSolrServer ThreadPool-1-thread-203:RetryExec@93] - I/O exception (java.net.SocketException) caught when processing request: Address already in use 2014-02-14 12:53:47,327 - INFO [CloudSolrServer ThreadPool-1-thread-203:RetryExec@106] - Retrying request 2014-02-14 12:54:24,740 - INFO [CloudSolrServer ThreadPool-1-thread-263:RetryExec@93] - I/O exception (java.net.SocketException) caught when processing request: Address already in use 2014-02-14 12:54:24,763 - INFO [CloudSolrServer ThreadPool-1-thread-263:RetryExec@106] - Retrying request 2014-02-14 12:54:39,121 - INFO [CloudSolrServer ThreadPool-1-thread-142:RetryExec@93] - I/O exception (java.net.SocketException) caught when processing request: Address already in use 2014-02-14 12:54:39,157 - INFO [CloudSolrServer ThreadPool-1-thread-142:RetryExec@106] - Retrying request Please let me know your suggestions.
