Dear,
I developed one application using openmpi in c++. This application should start internally (by system call) another application which is also developed in c++ and openmpi. When this external application is called with C system function the following messages are showed:

[localhost.localdomain:05275] 00B: Connectio to HNP lost
[localhost.localdomain:05276] 00B: Connectio to HNP lost
[localhost.localdomain:05277] 00B: Connectio to HNP lost


Please, could someone explain what is happening in this case?


Best,
   Carlos Santos
