- MC Production
  - Verbal report - tasks submitted to fill about 300k slots (~25M events, mostly EVGEN?)
  - Discussion about keeping track of future submissions to make sure don't run dry
- Group Production
  - Open-ended derivation production on data16 continues on 20.7.6.4
    - Full reprocessing of data15 with same cache mostly done with some tails
  - MC15c production with 20.7.6.4 for groups
    - Few requests submitted over the last few days
    - About 3k tasks finished already
    - Bulk should be complete by end of week
    - Need to decide of previous 20.7.5 production should be deleted in Rucio or obsoleted in production system
  - Memory Consumption
    - Have had high memory consumption in some of the derivation trains causing issues
    - Could be memory leaks but more likely fragmentation, so no easy fix
    - Short term solution is to split the long trains into two (longest are 10 carriages)
    - Does mean shorter (1-2 hours) jobs on sites, when we were trying to lengthen these
- Reprocessing
- CRC/ADCoS report
CA Cloud Squad Actions
- User DaTRI requests approved / processed (last week)
