    @RunLLM I am having a problem with topic replication. The topic replicates at about 10 messages per second, then for 2 minutes there is a sharp increase to 5k per second. Somewhere in the middle of the interval, replication to the remote cluster stops and does not resume. What should I do?

    The AI agent @RunLLM doesn't seem to be connected to this topic anymore. One way to get good AI answers about Pulsar is to use Deepwiki MCP with Claude Desktop / Claude Code or other vendor's tool. Then you can ask with a prompt such as "Check apache/pulsar and apache/pulsar-site with Deepwiki MCP to find an answer to this question:"
