HI Philippe,
??memory is to use --stats=yes and post the result here.
>Really, it is really the best way :).
I can not export log from my PC, because PC is isolated from internet.
Can I take a photo of log to you or Can pick up some key information from log
to you.
By the way, the size of email is limited to 40KB, am I right? so posting a
photo maybe not work out.

No, HG_CLEAN_MEMORY is not useful to use less memory.
It is only useful if you recycle memory, and you get
false positive race errors due to this recycling.
The best way to understand where valgrind/helgrind spends
memory is to use --stats=yes and post the result here.
Really, it is really the best way :).
If it takes too long to reach the end (or it crashes
before producing the stats),
you can from the command line use
vgdb v.info stats
to get the needed info while helgrind is running.
Philippe
