Any help with this would be appreciated? What tools are folks using to find leaks / fragmentation issues on mono?

Subject: [Mono-dev] Help with heap profilers
I suspect I'm seeing a low grade leak with ASP.NET, and I'm having a hard time getting any of the heap profilers to run correctly. Which is the recommended heap profiler? I assume it's the logging profiler. I run it with the following options:
And it seems to hang my process frequently both while running and during shutdown. Also even when it does not hang, I'm unable to get mprof-decoder to parse its output, I see the following exception quite frequently:
Unhandled Exception: System.OverflowException: Number overflow.
at Mono.Profiler.BlockData.DecodeHeaderBlockCounterDelta (System.Byte header) [0x00000] in <filename unknown>:0
at Mono.Profiler.SyncLogFileReader.ReadBlock () [0x00000] in <filename unknown>:0
at Mono.Profiler.ConsoleDecoder.Main (System.String argv) [0x00000] in <filename unknown>:0
Any help would be appreciated. I'm using mono built from mono-2-6 branch.
