Full error message:-
Error: Service(Telemetry(IoError(Custom { kind: Other, error: "Error parsing resolv.conf: ProtoError { kind: Msg(\"Malformed label: --\") }" })))
Got the above error while running the node in staging mode and it is working fine in dev mode.
How did I run it in staging mode:-
Firstly extracted customspec file using below command-
./target/release/substrate build-spec --disable-default-bootnode --chain staging > customSpec.json
After I have made few changes to it (changed staking,session and balances configurations) and then I have converted it into customSpecRaw file using below command
./target/release/substrate build-spec --chain=customSpec.json --raw --disable-default-bootnode > customSpecRaw.json
Then I got the output as
2021-09-21 02:46:00 Low open file descriptor limit configured for the process. Current value: 4096, recommended value: 10000.

and after this I started the node using-
./target/release/substrate --base-path /tmp/node01 --chain ./customSpecRaw.json --port 30333 --ws-port 9945 --rpc-port 9933 --telemetry-url 'wss://telemetry.polkadot.io/submit/ 0' --validator --rpc-methods Unsafe --name MyNode01
then got this error-
2021-09-21 08:46:29 Low open file descriptor limit configured for the process. Current value: 4096, recommended value: 10000.
