| 4493 | 00:30-00:30 | 00:00 | At the beginning of large offset_trajectory moves hex velocity faults sometimes occur. Even when the same large offset is made from the same starting position on the same track, sometimes it succeeds and sometimes it fails. (AW) | |
| 4471 | 02:02-02:03 | 00:01 | Getting ready to stack I sent the tracker to the lower right preset. Almost immediately I got a H6 Velocity Fault. | Reset the Fault hit abort tracker a couple times and resent the lower right preset. Worked without fault the second time. |
| 4494 | 02:10-02:14 | 00:04 | lrs2 cal script died because lrs2 server crushed | |
| 1696 | 02:44-02:44, 03:31-03:31 | 00:00 | Took out 42-2 for LTRSE. 03:31 UT Took out 55-3 for LTRSE. | |
| 4495 | 04:17-04:18 | 00:01 | While re-stacking it was noticed that mirror 89 is taking many iterations to move to correct place. Only moves a small amount each move (much smaller than the required move as shown by the vector in SAMS). It did eventually reach the correct position after many moves. | |
| 4461 | 06:52-06:52, 06:57-06:57 | 00:00 | uptime:46333 uptime:46666 Oscillations were seen in the x direction again tonight at the above uptimes. The second occurance was after a 11570" offset. | |
| 4496 | 09:02-09:14 | 00:12 | 20 mins into a trajectory all of a sudden the brakes engaged and both the tracker and TCS indicator lights went off. chksys revealed that both servers were defunct. More details in PR. | kill -6 the defunct servers and restarted them. Restarted all other servers as well as the tcs gui. After servers and tcs gui were restarted we successfully sent another trajectory. |
