Bug 3068 is about both the max and current size values being stored in
32-bit integers and the resulting math problems when either becomes
negative. Your cache_mem display making this clear.

One extra though comes back to memory. In the last round of fixes for
this 2x sizing complaint it was uncovered that memory pools were broken
for 64-bit math in 3.1/3.2. You may try turning them off and see if that
alters anything for the better.
