At 16:04 UT Noticed Cd had errors since 13:43 UT of the form:
2016.081.14:52:17.01#antcn#Error: Cannot get monitor info from antenna (8020002) 2016.081.14:52:17.01#antcn#Network I/O Timeout occurred on read/accept
Restarting fs seems to have fixed it. Called JMc who says that data during this period should still be valid. Just that antenna information was not being passed to the fs on time.
