FYI, the massive memory leak I've reported several times in before in 6.6x is still there in 6.61RC1 (build 4242).
Based on discussions on the forum I tried specifically to download with the Speed Limiter enabled and that's definitely a required part for the leak to happen, I'm fairly certain all the times I've seen it I've used the speed limiter at least part of the time. It also explains why I don't see the leak most of the time, I usually run without speed limiter.
I first downloaded some headers (without the speed limiter, memory usage looked normal afterwards), then enabled it and downloaded ~2500 files totaling ~2.6 GB, during which period the memory usage grew fast.
It's now been idle for many hours, after running Help->About it reports 200/200 (0) in cache use and the NB Pro process has a Virtual Size of 7.2 GB and a working set of 6.7 GB, definitely not normal.
OS is Windows 7 Pro, 64-bit. Statistics from Help->About, perhaps it'll help you pinpoint it.
Sqlite Memory Usage: 25847928
Sqlite High Water Mark: 54696848
Normal Blocks: 1 Memory:140312577
CRT Blocks: 0 Memory:8791768957168
Client Blocks: 1201136 Memory:0
I'll leave the process running for a few days in case you want me to check anything, the machine has 16GB RAM and it'll be fine for a while even with ~7GB "wasted" memory.
