Hi Barry,
this is an easy one...

No, invalid argument as pbind tells you.

From this output, you see that you have processors 1 and 2 (see first column).
> bash-2.03$ /usr/sbin/pbind -b 0 3761
> /usr/sbin/pbind: cannot bind pid 3761: Invalid argument
But you try to bind to processor 0 (-b 0) which simply does not exist --
therefore the invalid argument.
I am sorry for the rather sketchy explanation in my last mail. I thought that it was
obvious to use psrinfo to look the available processor number (at my Sun: 0, but at
your Sun: 1 and 2) and I also thought that there is always a processor 0.
Nevertheless, feel free to ask further questions.
Actually, we used this approach to hotfix a threading problem under heavy load on a
multiprocessor machine while development took place on a single processor one.
But later we discovered, that we had used C library functions which are not thread save.
After we fixed this, we could drop the pbind.
For all non-thread save functions, there are thread-safe (re-entrant) variants suffixed
by "_r". In our case, gethostbyname() was one of the culprits. We replaced it by
gethostbyname_r(), which lead to a somewhat more complex call syntax.
Oren, perhaps QF uses some non-thread safe functions (e.g. gethostbyname()). In my
experience, this can work for a long time, but if you switch to a real fast MP machine
(for production), the program starts to dump core.
On my machine, I looked in the following way for all "_r" suffixed functions:
