Hello All (cc sphenix-run-l for the announcement),

The meeting / working session focused on MVTX/TPC/TPOT FELIX -> BBOX/LUSTRE issue(s) will be today

Tuesday, June 11, 2024 from 12 pm - 3 pm, and below are the Zoom coordinates. I would like this to be a working session, i.e., after some discussion, really taking over the DAQ and trying / testing some things to set our baseline agreed current state and next tests/fixes to try.

There are a few issues, which may / may not be related.

1) There is the specific MVTX issue where data logging stops as seen below. This means for much of the running, MVTX data is simply being dropped.

2) There is a broader issue related to fluctuating logging rates to the buffer boxes. This is equality critical for stable running and also as we move towards bringing the much larger data volume TPC online. Jin has put together some useful slides that people should read through ahead of our session.

Jamie
