Hi.
I download the latest version 3.10.1,but helgrind use memory over 64G and got a
error from valgrind because of over the momory limit.
I used the option --stats=yes, I noticed that valgrind print message below
endless util to use 64G memory.
--28682-- univ_laog_do_GC enter cardinality 9614
--28682-- univ_laog_do_GC exit seen 6591 next gc at cardinality 9615
why?
DRD have not that problem ,but DRD 's message is not accurate comparing with
helgrind.

Hi.
Thank you for your reply.
Verison is 3.6.0,very old one,I will try version 3.10.1 and svn version,and
also try two options you said.

The memory needed by helgrind might depend on what your program does.
Typically, it needs twice the original, but it might be a lot more.
Which version of Valgrind are you using ?
In the SVN version, some memory improvements have been done.
The best is to get the latest SVN version, compile it,
then run with --stats=yes.
That will give some indications where the memory is taken.
More detailed information can also be obtained by using
--profile-heap=yes
