[Beowulf] pvm freezes

[Eduardo N. Asada]

Hi ,

I have noticed in my pvm programs and also with the examples provided with the 
package that when I run it several times, generally the program freezes in 
the third time (or in the second time). Then I have to interrupt it and run 
it again and this behavior repeats. 

What is the reason for this ? Is it related to the network card ? Does it 
happen with mpi also ?

Regards.
