  "message": "Core: fixed segfault with too large bucket sizes (ticket #1806).\n\nTo save memory hash code uses u_short to store resulting bucket sizes,\nso maximum bucket size is limited to 65536 minus ngx_cacheline_size (larger\nvalues will be aligned to 65536 which will overflow u_short).  However,\nthere were no checks to enforce this, and using larger bucket sizes\nresulted in overflows and segmentation faults.\n\nAppropriate safety checks to enforce this added to ngx_hash_init().\n",
