Examining a heap dump of Junos 19.3 test case reveals we are allocating java.math.BigIntegers to hold ranges – 32428 instances</p> <p>Each BigInteger costs us 64 bytes of memory, even when we could get away with much smaller storage – Integer/Uint32 and Long/Uint64 end up costing 16/24 bytes, hence we could potentially cut memory usage from ~2.5MiB to 500-800KiB.</p> <p>Track down the user and try to persuade it to use smaller Number classes.</p> YANGTOOLS-1206

The fix is to properly clamp possible values to the spec – which are built-in integral types for Range and Uint64 for Length.</p> Development Epic Link YANGTOOLS-652 Rank 0|i03wrz:
