It shouldn't have helped, but it seemed to. At the time I was more interested in getting the machine working than tracking down the problem. This is with a 2.2.X machine, and I am using mmap for most stuff in inn, which at one stage people advised against. Until quite recently we used to get blocks of nuls at the end of the active file if we had a crash - now I've a perl script which cleans this stuff up. (The machine is one of two NFS servers for about 50 diskless terminals, and sometimes runs out of mbufs)... David.
