Re: [Pharo-dev] Pharo6 with Ubuntu and OSSubprocess/threaded heartbeat crashes and problems

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