How to Valgrind processes near 256GB?

Gregory Czajkowski

I have processes near 256GB, need to run valgrind to determine why, but it runs out of memory ~60GB


==15336==     Valgrind's memory management: out of memory:

==15336==        newSuperblock's request for 4194304 bytes failed.

==15336==        62,289,825,792 bytes have already been mmap-ed ANONYMOUS.

==15336==     Valgrind cannot continue.  Sorry.


==15336==     more, depending on the tool.  On a 64-bit machine, Valgrind
==15336==     should be able to make use of up 32GB memory. 

How can it's limits be increased?

Thanks

If you google around then you'll hit:

This topic was also recently discussed on Valgrind user's list.

Kind regards,
