The antenna could not be set to PROG in both of main and sub reflectors. ALL PROG/MAN/STBY and PROG/MAN/STBY buttons did not work. After COSMOS3 was restarted at MTK only, this problem was resolved.

This was not resolved by restarting S99astqllsv and COSMOS3(cos3_cntl restart) on aste-mt1. Finally, Restarting /cosmos3/aste/rc3.d/S99astqlsv on aste-1c resolved this issue.

We noticed that there were many files under aste-1c:/cosmos3/naoj/log/wind/. shm_wind, shm_cadac and shm_pressure frequently received signal 15 from exec_weather. Why? Anyway, this is under investigation. Note this issue was not resolved by rebooting aste-v1c.

ACG reported timeout errors of dsactl1. This issue persisted even after S99astacg restarted on aste-1c.

We found dsactl1 did not reply to ping. The Ethernet port (192.168.118.1) of aste-1c was ok.

We could not try power-cycle of MAC because of no response from its lantap1.

FYI, MAC's temperatures were between 15 C and 17 C.
In the next day, we found the fuse of lantap was blown probably due to over current.
