Subject: problems getting stdout from spawned tasks

I'm having trouble getting the stdout of a number of slave processes
spawned by a master.

There is nothing in /tmp/pvml.<UID> and I tried a pvm_catchout( stdout ) but
still nothing.

The slave processes themselves spawn another process and the stdout
of these `grandchild' processes can be obtained without any problems. Could
it be that the grandchild processes are in some way interfering with the 
stdout collection of the slaves?

Initially I thought the slave processes were not starting at all. But this
is not the case as I can get the master to receive messages from them.

Any ideas anyone? It has me completely stumped.

Thanks,

Gareth.
