15:12UTC started an IA after struggling to LOCK_ALS and seeing the ALS error signals weren't great.

IA finished at 15:33UTC, but since then I've been struggling to get DRMI, PRMI locks pretty easily but DRMI struggles even with some decent flashes, POPAIR_B_RF18 can't seem to flash above 120. Lots of ALS locklosses too, sometime from WFS sometimes for no apparent reason.

Follow up on Dolphin crash:

I looked at the logs for the front ends which had an issue at 01:05:25 PDT (lsc0, oaf0, susb123, sush2a, sush34, sush56), nothing was logged at this time.

All the IOP models experienced a very large timing glitch at this time. The size of the glitchs are

iop model cpu max (mS)
oaf0 24.3
lsc0 23.4
susb123 15.7
sush2a 18.7
sush34 18.7
sush56 15.7
