Crash during ascent after dropping boosters #2716
Comments
Journal! new scenario, but same failed check and similar conditions. Crash occurs during crewed reentry, while the decoupled service module is slowly dropping back and bits of it are exploding. Bits are somewhere around 4km distant. Happened 3 times in a row, got a journal for 3rd instance. |
supporting evidence that it has something to do with the decoupled part: reloaded, deleted it via tracking station, went back to capsule, no crash |

The bug appears to be in |
Seen twice; not reproducible at-will, so no journal. Both in Gallai.
From FATAL.log:
F0909 21:55:24.457835 9920 not_null_body.hpp:33] Check failed: other != nullptr
From INFO.log, crash happens both times after a bunch of "removing vessel"/"destroying part" messages
In both cases the scenario was the same: launching a rocket consisting of 2 stages plus a pair of solid boosters, the boosters were dropped a few seconds ago. Some parts have been blowing up, presumably from aerodynamic stress. It's possible enough time elapsed for the dropped parts to fall out of physics range.
Each solid booster (ROE-Algol1) has a pair of separation motors attached (ROSmallSpinMotor).
One difference in the second instance: one of the Algols blew up (testlite) shortly before running out of fuel. Its spinmotors would have become debris a few seconds before staging the remaining Algol.
