Yes, one of my customers is having exactly the same problem. FMC is 10.0.2.
Additionally there is also the message "Talos Communication Daemon not updating health" for FMC and two FTDs.

Since both Cisco_DNS_Intelligence_Feed and Sourcefire_Intelligence_Feed are failing, I’d check the FMC logs for the exact feed-processing error rather than focusing only on TCP connectivity.
You can start by checking /var/log/messages around the time the alert occurred. If there’s no useful information there, collect the relevant feed-update logs and open a Cisco TAC case, especially since this is a critical alert. Another community reply on this same issue also recommends checking the logs and contacting TAC if they don’t reveal the cause. <Link url="https://community.cisco.com/t5/network-security/issue-with-security-intelligence/m-p/5573685" title="Cisco Community discussion"/>.
What exact FMC 10.x build are you running, and did this start after an upgrade or happen unexpectedly? That information may help identify whether it’s a version-specific issue.
