Hb.c and fabric.c warnings during security scanning

Operations
1

Hello,

We regularly see these warnings (below) on a daily basis, and based on the regular cadence in which they appear, they look to be related to a security scan.

Is there any risk involved, or are these warnings benign?

WARNING (fabric): (fabric.c:1820) r_msg_sz > sizeof(fc->r_membuf) 1048582 WARNING (hb): (hb.c:4213) error allocating space for mesh recv buffer of size 369296137 on fd 67

Thank you

Something is sending a message (likely garbage) to Aerospike heartbeat port (default port 3002). The message fails a message size sanity check. We often see this when someone is running a security/port scanner against the service. Please check and ensure that you aren’t running the database service in a way that is accessible from the public internet.
