Thanks for your response.

The only content in the folder is the *rcl.txt files, the rootkit files, 
agent.conf and ar.conf. They are all readable by the ossec group.

I have a similar set of files on the agent.

I do have the "ossec-remoted: DEBUG Sending file 'merged.mg' to agent." log 
message in the manager logs.

Is there anything else I can try?
