After checking with the way other programs do it I think distcc's use of
mmap in dcc_r_plain is correct. (Wayne, could you check?)
I think you may have found some kind of kernel NFS bug. Could you
please do a couple more things to help narrow it down?
1 - get an strace of the client, with something like this:
DISTCC_HOSTS=otherhost strace -f /tmp/trace.out distcc -c hello.c \
/disksites/hello.o
2 - get a tcpdump of the NFS traffic by running something like this:
tcpdump -s8000 -w /tmp/distcc.tcpdump 'udp host nfsserver'
Press C-c after running the compilation.
Thanks,
Martin
