thanks for the hints/fixes, I'll apply them shortly. :)

Okay, weird, but what the heck, it doesn't break anything ;)

It's a bit of a catch-22 really - if you add a `return (NULL);' there
other compilers (the Sun CC for example) complain that ``a statement is
never reached''.. *sigh*

Since all other processes are either sleeping or waiting on some mutex
it's likely that the problem is in the network plugin, but I'm afraid I
can hardly tell what's going on here. Would you re-compile with
``--enable-debug'' to get backtrace with debugging sumbols? Also adding
`-O0' to the CFLAGS would help - the `write_part_number' originally only
has four arguments, apparently the compiler is passing something else on
the stack here..

Sure, go ahead - though I doubt I can use it much.. But it's worth a try
;)
