Thanks for that.  I really need to see the netstat and backtrace on
both the client and server though.

You might try commenting out HAVE_SENDFILE in config.h after
configuring, then doing "make clean all", in case there's a bug either
in RedHat's sendfile or in distcc.

Attaching the debugger probably interrupts the sendfile() system call.
distcc (in CVS, not in 0.8) will cope with this and restart it.  I am
not sure why transmission would hang in sendfile unless there was
something wrong on the other machine, which is why I need to see its
backtrace.

Are the two machines in question on the same ethernet hub, or is there
a firewall or something between them?

Thanks,
