I am trying to run a Geth node on an AWS EC2 instance. I am able to start it, and it runs fine for a while, but keeps crashing periodically and not leaving much in the log.
The EC2 instance is a T2.Medium, so it has 2 vCPUs and 4GB of RAM. Output of commands about instance:
ubuntu@ip-127-0-0-1:~$ uname -a Linux ip-127-0-0-1 4.4.0-1062-aws #71-Ubuntu SMP Fri Jun 15 10:07:39 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux ubuntu@ip-127-0-0-1:~$ cat /etc/issue Ubuntu 16.04.4 LTS \n \l
I have allocated plenty of storage for the blockchain (500GB) and it is not close to full.
I have tried running Geth as a
systemd service as mentioned here, as well as every other method listed. Some examples include:
geth --cache=1024 --rpc --rpcapi "eth,web3" 2> gethlog.txt screen -dm bash -c 'geth --cache=1024 --rpc --rpcapi "eth,web3" 2> gethlog.txt' nohup geth --cache=1024 --rpc --rpcapi "web3,eth" &
Again, the node starts and runs fine for a long time (I am able to exit the SSH session with the instance, reconnect, and I am able to attach to geth and even
curl against the RPC) It seems like after running for a long period of time, geth shuts down. The only time I caught in the above-mentioned
gethlog.txt, it was logging as if it received a shutdown command (
Already shutting down, interrupt 9 more times for panic.)
I'm thinking something has to be wrong with my EC2 environment. I'm sure I'm missing something obvious, but I've been struggling with this for weeks!
