Which is a mostly irrelevant number.

You've got 1.4G in use, 5.3G of disk cache, 165M of buffers and 667M
free. That doesn't seem unreasonable. If an application needs more
memory the amount of disk cache will decrease. As I said in an earlier
email, the problem is that the application is trying to allocate a bogus
amount of memory, not that you have a memory problem.
