It looks pipe on vax is broken (at least on simh). The following simple command also fails: # gzip -c /netbsd | zcat > /dev/null zcat: unknown compression format "gunzip base.tgz && tar xpf base.tar" seems working, and INSTALL kernel and GENERIC with options PIPE_SOCKETPAIR also work fine. Compiling kern/sys_pipe.c with -O0 doesn't help.
Setting BIG_PIPE_SIZE to 32KB or even 63KB in sys/arch/vax/include/param.h seems to get around the problem. An additional bonus is that scp to copy files to the local host seems to also work now.
