It maintains buffers of size FD_SETSIZE (1024 on Linux)*, so an fd<br>
parameter** >= that, could probably trigger such an error.<br>
Maybe you could put a halt in whichever method in OSSubprocess/OSProcess<br>
calls the primitive triggered when condition occurs, to see if that is the<br>
cause?<br>
If so, identifying *why* you end up with fd's that high (which, afaik, isn't<br>
normal), will probably lead to a workaround/solution...<br>
