I have an MM 5.1 with 2 MAS/1MSS and 1MN. This morning all MWI stopped working. First thing in the logs were that there was an issue with time. The time was off between the servers. We updated an NTP address on the MSS and the MAS Servers picked it up right away. However, the MWI is still not processing lights/no lights. Does this require a reboot?
