VIRT Memory so much!

ubuntu server 12.04 x64 kernel 3.5.0-27-generic

VIRT Momory use 164m, too much than ubuntu server 10.04 x64

What is the problem you want we solve? Do you get the same using pthreads? If , not how do you reduce this consumption?

When create one thead use VIRT memory:

Ubuntu server 12.04 x64, pthread_create, Less 1M

Ubuntu server 10.04 x64, boost::thread, About 10M

Ubuntu server 12.04 x64, boost::thread, About 80M

When I use ‘boost:thread’ create more than 1000 threads, About 80G VIRT memory, how can I solve it?

It would be useful if you can provide a program that shows this and try it on other versions of Boost and see if this is a regression on Boost.Thread or a regression on how Boost Thread uses Ubuntu resources.

Do you have ciphers for Ubuntu server 10.04 x64, pthread_create?

I can not do anything if you don't collaborate.
