You might be seeing something related to this, especially if you're 
doing stuff with FTP and have other services on your LVS using persistence:

The patches for this went into 2.4.32:

So you might need to bring your kernel up a few versions, if at all 
possible.

Of course, you may not be using the FTP helper at all, in which case we 
might need more info. Is your kernel compiled to provide LVS debug 
support? You have if you have the /proc/sys/net/ipv4/vs/debug_level 
sysctl; if not you'll need to recompile anyway to switch it on. But 
we'll cross that as and when necessary :)
