Multichain chain not responding issue

Question

While I am trying to make rpc calls to multichain chain, the chain is not responding and I got as below:

multichain-cli chainv11 getinfo
{"method":"getinfo","params":[],"id":"18842647-1590488892","chain_name":"chainv11"}

error: no response from server

And also got the same response while trying to stop the chain:

 multichain-cli chainv11 stop
{"method":"stop","params":[],"id":"58684957-1590489284","chain_name":"chainv11"}

error: no response from server

and I couldn't get response until I rebooted the server .

Answer 1

Yes, this simply means that the node has stopped running, so it is not responding to API requests. The question is why it stopped running, perhaps it was issued a stop command, or a kill command was run on the command line. If neither of these are true you can look in debug.log for more information.

Comments

neither of the mentioned commands issued, and while the issue happened again, checking debug.log doesn't contain any error.Below are the last lines within debug.log and during this hanging, nothing wrote in debug.log file
