After upgrade to MD19.0.3, MDSPAMD is crashing

Updated to 19.0.3 (running x64 on Windows 2016) this morning at 7:15am. Seemed successful. Prompted to reboot server. Did that. Now seeing this on dozens and dozens of messages today in "antispam.log"

...... Fri 2019-07-19 07:57:04.958: * MDSpamD Error: could not process d:/mdaemon/queues/inbound/md50000478190.msg Could not connect to host.

which sends the message into the HOLD queue, and and this(below) in "SYSTEM.LOG" ever since the update. I have had to turn of Antispam to stop this madness. CAN ANYONE HELP?
