Happened again - here is the backtrace info:

AdvChild (7222) died signal=6
Child (7222) Panic message: Assert error in STV_alloc(), stevedore.c line 71:
  Condition((st) != NULL) not true.

  },

The request information shows that it was apparently fetching a 1GB file from the backend and trying to insert it into the cache.
