Hi, In McKusick's book "The design and Implementation of the 4.4BSD Operating system", in the "Buffer Management subsection of the I/O system overview, there is a a sentence that says "...depending on available memory, a system is configured with from 100 to 1000 buffers.." referring to the number of struct buf* in the integrated VM/IO buffer cache. I have plenty of RAM in my computer, but it seems like there are always 1000 buffers configured (empirical observation, if I try to allocate one more after that the system freezes). How do I increase the nubmer of buffers? More consicely, how do I allocate more memory to the buffer management subsystem? Thanks Eno
