Hi, all:
I have a proxy application wroted in go, and try to use pprof to find
out memory usage in Go, but it seems strange that memory usage
showed in top, pprof tools and http://localhost:6060/debug/pprof/heap,
do not match each other.
Top:
RES: 266M
20M
pprof --text http://boromir:6070/pprof/heap
85M
What does it mean ?

This is the amount of physical RAM dedicated to your
program right now. It includes parts of the program text
and the allocated heap, but it may not include all of it,
if some of the text has not yet been paged in from disk
or if some of the heap has been paged out to disk.

This means that the heap profiler is tracking
159 currently allocated objects taking up 20 MB;
overall it has tracked 152,494 objects taking up 28.7 GB.
The @heap/1048576 means that the heap profiler
is trying to sample about one byte per half megabyte
(there's an implicit divide by two due to a mistake
made long before Go was an idea).
If you've got 159 objects totaling 20 MB, that's
125 kB each, so sampling one byte per half megabyte
means you're probably hitting only 25% of the allocations,
so an estimate of the total amount in use would be
20 MB / 0.25 = 80 MB.
> pprof --text http://boromir:6070/pprof/heap
> 85M
I was close. In fact the calculation I just did is done
for each of the lines following the heap profile line,
so it ends up a bit more accurate. But it's still an
estimate, and only an estimate of what's in use right
now. The process might have allocated more
memory and freed it already, but that memory is
sitting in free lists, not given back to the operating
system.

Over the lifetime of the program the memory allocator
has served requests for 114 GB.
> # Sys = 1410111736
It asked the operating system for 1.4 GB.
This number is buggy: the garbage collector
recently started allocating and returning
temporary memory during garbage collections,
and it doesn't adjust this properly when it returns
the memory. Normally this number should be
the sum of the XxxSys numbers below.
> # HeapAlloc = 85545416
This is the exact number of bytes allocated right now.
pprof was pretty accurate.
> # HeapSys = 275906560
275 MB is being used by the heap.
That matches what top said, so that's good.
This includes memory reclaimed by the
garbage collector and not yet given out again.
It's likely that even though 85 MB is in use right now,
earlier in the program there was more memory in use,
probably around 140 MB, which is why the allocator
let the heap grow to 275 MB.

Hi, Russ:
Thank you very much, for the details descriped above.
According to the report of pprof, there was some memory leak in my database
application, called beasdb, something like memcached with a log-structure store in disk.
After running almost one day, the memory used by beansdb increased quickly,
about 100M per hour, and it never stop.
In the heap profile (was attached below), there are many objects not freed by GC:

They were buffers used to store record data, should been freed after sending to client.

--------------------------------------------------------------------------------------------------Something strange was that, I have two beansdb deployment, one for text (2k per record),another one for images (100k per record), only the later one had memory leak problem.How are the larger memory blocks (>32k) managed by GC? Are they managed different from small memory blocks?How can I find why the data buffers are not freed by GC ?Thank you very much. I will publish the whole code a bit later, if it can help.

Are you using the 386 or amd64 port?
It's possible that the big images stick around
because of false positives in the conservative
garbage collector.

Maybe, I should manage the read buffer manually,
re-use the buffer in the same goroutine, to stop it
from allocing new one.
If the memory leak problem can not been solved in Go,
I HAVE to re-write it in C instead, very sadly.

If it's amd64 it's not the conservative garbage collector issue.
Are you sure that you are releasing all the references
to the Records being created? The stack you showed is
entirely reasonable if the Records are being kept around
somewhere.
