The limit is determined by /proc/sys/net/core/wmem_default in Linux. The problem is that the parent blocks till the child exits and then starts reading, so in case the buffer gets filled up, we have a deadlock. -- Siddhesh Poyarekar http://siddhesh.in _______________________________________________ ast-developers mailing list [email protected] https://mailman.research.att.com/mailman/listinfo/ast-developers
