Restarting Document Cache Process
Under the DGraph cloud ( https://cloud.dgraph.io/_/explorer ) choose the right namespace and query the cursor.
query Cursors {
queryCursor(first: 10, offset: 0) {
id
cursor
}
This query should return similar response:
Based on this response, current cursor is at block 36215565
Compare this block with number of current block ( on blockchain explorer ). If they differ much and this cursor is not updating, it means that GraphQL sync has been blocked
Login to AWS and find the running document cache processor instances ( https://us-east-1.console.aws.amazon.com/ec2/home?region=us-east-1#Instances:instanceState=running )
Connect to the console of instance for particular chain and environment
Run the following command to get the latest logs
systemctl status hypha-doccache-processor.service
journalctl -u hypha-doccache-processor.service -n 100 -f
Try to run the service again with
systemctl start hypha-doccache-processor.service
Manually start the process by going to the folder on AWS instance
cd /home/ec2-user/app
and running the command
./hypha-doccache-processor ./config.yml [BLOCK_NUMBER]
Running manually the process would also show you the error, so you could debug it that way
Replace the file hypha-doccache-processor on ~/app with a new file using scp
