pfSense 2.4.4 DHCP Relay issue

I am using Windows Server as my DHCP server for several subnets, and have had pfSense setup as a relay. All was working fine. I just upgraded to pfSense 2.4.4 and since then I have noticed that I have had issues with devices not being able to get IP addresses. Android devices for example will come back and say it could not obtain an IP address. I initially tried to restart the DHCP server service on the Windows server but that didn't make any difference. However, I restarted pfSense and it began working. It was okay for a couple of hours and then I started having the same issues again. The next time I just reset the dhcrelay service on pfSense and it began working again.
I really don't know much about the DHCP Relay or how it works. Has anyone seen the same issue or have any suggestions? I will probably put a CRON job in to restart the dhcrelay service every hour, but that seems like a bandaid and not a fix.

Just want to say that I also have this issue on 2.4.4. I've checked the logs to find this
Nov 13 09:43:51 dhcrelay Disabling output on BPF/vmx1.2202/00:50:56:94:4b:66

repeated for each interface setup for DHCP Relay. Restarting the service fixes it, but I'd rather not take mcarson75's solution of setting up a cron job to fix this.
