High memory usage : Partially filled arrays

[seb816]

Hello,

Recently, I update our nuget package from 3.21.50 to 3.21.130
We remarks an high memory usage since the upgrade.

When I look at the dump, a lot of memory is wasted by arrays which are partially filled and seems to come from 'CachedStatement'
Thoses arrays wasted are essentially OraArraySegment[] and Int32[]

If i look on 1 'CacheStatement' , thoses properties seems to be the cause :

@seb816 Can you share a test case that can reproduce the high memory usage reliably? If not, can you share the diagnostics you've collected that would allow the ability to identify how consumed memory is accumulating? Alternatively, you can share the test case and diagnostics with us securely by opening an Oracle Support service request.

Closing this issue for now. I will reopen once we get more data on how to reproduce the behavior.
