Greetings, everyone, I am doing some simulation that needs to allocate as many nmbufs as possible. I could not figure out how to set nmbufs to be the maximum value allowd by my physical memory. I tired to mannual set it to be a huge number, for example, 128MB/128B=1M (I have 196M memory) and used netstat -m to monitor the real allocated nmbufs. However, when it reached some value lower that a 1M, a kernel page fault happened. It seems to me I also need to increase the maximum kernel memory size seperately. Can someone tell me how to do it right? Is there a simple formula to estimate the number?
