I have encountered the same problem while doing the groovy pre-release
test of ethzasl_message_transport. My understanding is that the
pre-release farm is running on an old cluster and is in a somewhat shaky
state. I have also encountered funny errors like "Too many open files"
and others, clearly not linked to my stack.
I unfortunately have no useful advise on how to work-around this
problem, I can just say that you are not alone.
Kind regards,
Stéphane
