Many thanks ikegami,

I tried wait_all_children (see answer below) but without success.

Somehow the $pm->finish (I also tried a plain exit) with the same result aborts the whole writing?.

I guess that somehow the call to syswrite produces a decoupled process in the remote machine than is in charge of fulfilling the writing (since it is a huge message). When the exit of the forked local child occurs the remote process is aborted?
