First scan started on 042-1814a (Lim). There were too many “vdesk” running on newsmerd, all terminated by Jamie. Run vdesk again and “drvon” for about 15 minutes until the connection comes back. 1954UT fs crashed, scans 042-1957b to 042-2024 were probably missed as well (Lim). 2022UT fs-auscope restarted, next scan is 042-2028 (Lim). 2120UT Error: Cannot get monitor info from antenna (8020003); #antcn#Network I/O Timeout occurred on write 2153UT DrivePC (sys26m) and Hobart machine rebooted, that sort of cleared the problem, which was a result of power failure. Next scan 042-2159 . Missed scans: 042-2119 to 042-2157 (Lim). 0812UT - There seemed to be a power failure. Tried restarting the FS and running the schedule however that showed up The allocating memory for antenna monitoring error. Rebooted the drivepc by using the command “rem_reboot -r rakbus sys26m” on observer@newsmerd. The RA/Dec/time values which were static earlier, now started changing (as seen on rack 1 through the camera). Did “source=disable” on the FS to resume the schedule. Scans 043-0811 to 043-0844 affected (Prad). 0910UT - Drives weren't ready on time for the last few scans. “drvon” on vdesk a few times seemed to have done the trick. Left drive (on) delay causing the problem? Scans 043-0848b to 043-0908 likely to have been affected (Prad). ================================ aov044kg READY ================================ 2020-02-13 05:24:52 aov044, Koganei11, Ready and start message Dear colleagues, Koganei11 was ready for aov044 session and I was able to confirm the schedule started with first source oj287.
