Node already in use?

[LourensThalen]

Ethereum Wallet says (after I updated Geth) there already is an instance running. It's not, at least, not that I know of.

System information

Version: `0.8.3`
OS & Version: osx
Node type: `eth/geth(default)`

What's the result of ps aux | grep geth?

/Applications/Mist.app/Contents/nodes/geth/mac-x64/geth --testnet --fast --ipcpath /Users/ev/Library/Ethereum/geth.ipc

we're looking for geth and ipc path here.

Maybe you could do a one-time process kill and start the 0.8.3 Mist version again.

@LourensThalen as Ethereum-Wallet will try to connect to the default ipc path at ~/Library/Ethereum/geth.ipc (if not changed via --ipcpath) it will think that no geth is running - as your datadir changed on the running system installation of geth:

/usr/local/opt/ethereum/bin/geth -datadir=/usr/local/Cellar/ethereum/1.4.12/.ethereum

Thus Ethereum Wallet will try to take control of the node management and start geth on its on which will, however, fail as the default udp port 30303 is already being used by the externally evoked geth instance.

So you will either have to change geth's --datadir to its default (you can simply omit it) or evoke Ethereum Wallet using the adjusted --ipcpath flag. To accomplish the former you might have to edit geth's launchagents plist file as this suggests.

Closed as probably resolved.

+1. I get the following: ps aux | grep geth timsiwula 2861 0.0 0.0 2424188 460 s000 R+ 8:23AM 0:00.00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn geth
