  • Following error messages are found or OOM dump is generated which indicates OOM occurred.
    • Reason for shrink: Adjust NVM memory size XXXXXXXXX
    • Out of memory for <allocator>, size XXXXXXXXX, alignment=1B, flags 0x0, reason GLOBAL_ALLOCATION_LIMIT (early exit)
  • However, you noticed that GLOBAL_ALLOCATION_LIMIT is still much larger than sum of AB (Allocated bytes by allocators for heap and stacks) plus SHARED_MEMORY

    GLOBAL_ALLOCATION_LIMIT (GAL) = 3tb (3298534883328b), SHARED_MEMORY = 171.77mb (180117504b), CODE_SIZE = 2.34gb (2520866816b), OOM_RESERVATION_ALLOCATOR_SIZE = 96.14mb (100810752b)

    PID=12345 (hdbindexserver), PAL=3tb (3298534883328b), AB=2tb (2199023255552b), UA=0, U=2tb (2199023255552b), FSL=0b, FMC=0b
