Common Issues and Troubleshooting

Subnet blocks are not being mined.
1. First confirm that the Subnet nodes are able to communicate with each other through the network layer. Run the check peer script generated/scripts/check-peers.sh the number of peers should be one less than number of subnet nodes. For example, if there are 3 Subnet nodes in total, each node should have 2 peers.
2. If the nodes are peering but still not mining, it could be a low memory issue. In Docker configs you can try to increase memory or swap. Then, in case of fresh Subnet, delete data and start the nodes again. !
3. Docker engine in Mac OS can be inconsistent after long-running or high-load. It could help to restart the machine and hard reset the subnet to get it running.
Subnet node does not boot with error log Fatal: Error starting protocol stack: listen unix /work/xdcchain/XDC.ipc: bind: invalid argument

This is due to the volume mount path being too long. The mounth path is your current directory (also can check with pwd command). Please move the generated folder to a shorter path and try again.
Docker image startup fails with SIGKILL or Error code: 137 found in logs. (Issue found in Frontend image)

This error occurs because Docker ran Out Of Memory (OOM). You can increase the memory limit in Docker settings

This will check your current block in Subnet

This will check the number of peers of your Subnet node
