From: Andi Kleen <ak@suse.de> Date: 20 Feb 2003 08:52:46 +0100 That's probably because of the lazy ICMP socket locking used for the ICMP socket. When an ICMP is already in process the next ICMP triggered from a softirq (e.g. ECHO-REQUEST) is dropped (see net/ipv4/icmp_xmit_lock_bh()) Good spotting Andi. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
