memcache and nginx

[Sean Allen]

have the same setup on two machines, identical configurations but the  
newer machines reports the following a few times an hour:

2008/05/07 16:36:28 [error] 5969#0: *128011 memcached sent invalid  
trailer while sending to client, client: 66.60.241.3, server:  
micro.thepinkpatch.com, request: "GET /s-Pcpx300BT24p/lp HTTP/1.0",  
upstream: "memcached://127.0.0.1:11211", host: "micro.thepinkpatch.com"

My google skills failed me. Is there a solution to this?
