Running a bitcoin node on regtest network fails

Question

I'm trying to run a bitcoin network on regtest with this version of bitcoin node so I can test out bitpay's insight-ui block explorer.

Running on regtest I get this repeating error

Assertion failed: (psocket), function Shutdown, file zmq/zmqpublishnotifier.cpp, line 92.
[2017-05-19T00:42:44.515Z] warn: Bitcoin process unexpectedly exited with code: null

[2017-05-19T00:42:49.517Z] info: Starting bitcoin process

Which eventually becomes

After which I have the reoccurring error

Thoughts on how I can get this up and running with a block to look at so I can use the block explorer?

Answer 1

Okay I figured it out. What was happening is there were some other bitcoind processes that had zombied out and were listening on the port this process was trying to access. I ran this command to kill the other processes

killall -9 bitcoind

Also, to create more blocks on regtest (while in the your node directory) use this command.

./node_modules/bitcore-node/bin/bitcoin-0.12.1/bin/bitcoin-cli -datadir=/Users/harshagoli/mynode/data -regtest generate 150
