I’ve been syncing a participation node on a Linux server for a few days now. I have approximately 11 million blocks synced, but the node seems to have stopped syncing and I can’t seem to figure out how to troubleshoot the issue.
Here’s the output of ./goal -v:

go-algorand is licensed with AGPLv3.0

I’m not sure why it suddenly stopped syncing, but I would really appreciate any assistance. Thanks!
