I am working with AmazonSQS. I am using threads to read content from there, after a short time, I get the connection pool error

this is my thread logic

ReceiveMessageRequest request = new ReceiveMessageRequest(#url);
request.setMaxNumberOfMessages(#getMaxMessagesPolled);
request.setWaitTimeSeconds(5);
while (true) {
  List<Message> messages = new ArrayList<>();
  try {
    messages = awsService.getMessages(parameters, request);
  } catch (Exception clientException) {
  continue;
  }
  for (Message message : messages) {
      //process
      awsService.removeMessage(parameters, message);
    } catch (Exception e) {
      continue;
    }
  }
}

error :

com.amazonaws.SdkClientException: Unable to execute HTTP request: Timeout waiting for connection from pool

As I know the default connection pool size is 50. I do not have >50 threads.

Thanks

Did you close your S3 objects? – smitty_werbenjagermanjensen Apr 10 '19 at 14:33
I do not use any S3Object – javagc Apr 10 '19 at 14:58
Can we see a snippet of the code which may be causing your errors? – smitty_werbenjagermanjensen Apr 10 '19 at 16:04
I have updated my question – javagc Apr 11 '19 at 09:56
Do you really (1) allocate an ArrayList to have it immediately thrown away and (2) completely ignore exceptions? The exceptions may be showing something else. – stdunbar Apr 16 '19 at 21:27

@javagc Were you able to resolve? I am getting the same issue. – Sagar Oct 04 '20 at 20:57
