https://www.multichain.com/qa/tag/unresponse Powered by Question2Answer https://www.multichain.com/qa/9204/explorer-often-no-response I installed &amp; run explorer following README:<br /> <br /> * python -m Mce.abe --config chain1.conf --commit-bytes 100000 --no-serve<br /> * nohup python -m Mce.abe --config chain1.conf &amp;<br /> <br /> The explorer run very well. but often no response over a period of time. so I have to kill explorer process and remove sql file and rerun the explorer.<br /> <br /> I check the nohup.out and find some error like:<br /> <br /> * error: [Errno 104] Connection reset by peer<br /> <br /> * error: [Errno 32] Broken pipe<br /> <br /> * Exception happened during processing of request from ('61.151.178.170', 38796)<br /> <br /> I check the node, it's ok for my application, and only explorer no response.<br /> <br /> I find some solution in internet, someone suggest to use try ...except to avoid it, but I don't know where can I add the code. I guess this should be done in explorer source code.<br /> <br /> I don't know whether there's bugs in explorer or some other reason.<br /> <br /> Help me pls.<br /> <br /> I check 2750 port : netstat -apn |grep 2750, and found too lots of CLOSE_WAIT, hope useful for the issue.<br /> <br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 0.0.0.0:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0.0.0.0:* &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;LISTEN &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;23772/python &nbsp;&nbsp;&nbsp;<br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;209 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;141.8.144.17:35012 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CLOSE_WAIT &nbsp;- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;209 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;100.43.85.160:56202 &nbsp;&nbsp;&nbsp;&nbsp;CLOSE_WAIT &nbsp;- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br /> ..................................<br /> <br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;117.136.86.44:25351 &nbsp;&nbsp;&nbsp;&nbsp;ESTABLISHED 23772/python &nbsp;&nbsp;&nbsp;<br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;605 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;202.100.35.27:9575 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CLOSE_WAIT &nbsp;- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br /> ................................<br /> <br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;209 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;100.43.91.105:41016 &nbsp;&nbsp;&nbsp;&nbsp;CLOSE_WAIT &nbsp;- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;258 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.255.250.97:64988 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CLOSE_WAIT &nbsp;- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br /> tcp &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;209 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 172.16.249.12:2750 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;100.43.91.105:46932 &nbsp;&nbsp;&nbsp;&nbsp;CLOSE_WAIT &nbsp;- https://www.multichain.com/qa/9204/explorer-often-no-response Wed, 04 Apr 2018 07:38:32 +0000
