kangkaisen opened a new issue #1637: Curl Mini load timeout
URL: https://github.com/apache/incubator-doris/issues/1637
 
 
   **Describe the bug**
   Yesterday, Our user run a large hive to doris job, which had 700+ doris Http mini load, but a one http mini load get the following error:
   ```
   curl: (28) Operation timed out after 600746 milliseconds with 0 out of -1 bytes received
   ```
   the curl cmd:
   ```
   2019-08-13 16:32:16,962 ERROR curl -m 600 --location-trusted -u xxxx:xxxxxxxx -T localfile   http://xxxx:8410/api/data_flow/app_log_sdk_mart_mv/_load?
   ```
   
   1 I put the local file manually again， which was successfully. **which means the file itself is normal.**
   
   2 I grep the fe log by load label, **I found the http mini load request didn't reach the doris FE Server**
   
   3 After check the network monitor, I ensure the network is normal.
   
   4 Finally, I check the TCP monitor, I found:
   
   ```
       7150 times the listen queue of a socket overflowed
       7150 SYNs to LISTEN sockets dropped
   
       TCPBacklogDrop: 433410
   ```
   So I think the reason for curl cmd failed is TCP ListenOverflows.
