Am I correct in thinking that there is a message length limit for the SUNMP
port of PVM3.3.3 not present in the SUN4 and SUN4SOL2 ports?
I'm running on a twin processor sun sparc20 (under unpatched Solaris 2.3).
The fault seems to occur when a message over ~1M is sent - there is no
complaint when the buffer is being packed but when it is sent the sending 
program locks up and eats processor time. This doesn't occur on the other 
Sun architectures I use.
