I have two redundant ACE mods, running 3.0(0)A1(6.1). They appear to be corrupting/dropping ping packets, but only to "reals" that live on the ACE. If I ping through the ACE no problem, if I transfer large FTP file to "real" or VIP no problem. However, if I ping the "reals" and capture traffic with a sniffer, I see bad check sums, missing packets, etc. It displays this behavior to all servers that live on ACE, system resources and network load are not an issue.
