- | * When I set up the delaylive, noticed a series of clock-jumps on the dbbcho starting at 5:00UT, then again at 6:00,6:30 and 7:00. Clock jumps are on | + | * A series of clock-jumps on the dbbcho on the order of -0.015us (Lucas). |

- | a. Have not reset the dbbcho (yet) as the summary script reports okay delays and samplers. Appears stable at the moment but if it jumps again I will | + | * Katherine 12m |

- | b. Jumped again at 8:00 UT, halted and reconfigured dbbcho. Missed scan 057-0821b, 0825. | + | * Flexbuffke got into a nasty state and wasn't happy (Lucas). |
- | c. Called Jamie. clkoff isn't actually indicative for dbbcho problems when hooked up to Hobart12m. So don't worry about delaylive hb. | + | * The current fix is to (halt obviously), umount all the drives, remount them, restart jive5ab and re-setupsx (Lucas). |
- | | + | * Due to wet season and power outages. Have to restart the connection and Fluxbuff. |

- | * Flexbuffke got into a nasty state and wasn't happy. The first sign was the data rate on Grafana went from the 'normal' smooth 3Gbps scans to ugly, | + | |
- | spiky and somewhat random data rates. Another sign was the number of dropped packets in “mk5=evlbi?” – maybe we should add this to katherine midob? | + | |
