-----------------------------

    Attachment: infinispan_memcached.log


Hi guys,

We are preparing sample ruby script to demonstrate error.
In attachment you can find full stacktrace that I can found in "infinispan_test.log" file in bin folder.

I run infinispan from all distribution with default script 

"./startServer.sh -r memcached" 

I can enable additional logging if it would help you.

the broken pipe exception i think comes from client forcefully closing connection to server when invalid response is recived.
from client log:

D, [2010-08-19T13:37:58.455827 #21027] DEBUG -- : get objects/all_sections from <MemCache::Server: localhost:11211 [1] (NOT CONNECTED)>

> We have ROR application that uses MemCached for distributed cache.
> As we have many issues with MemCached and its "clustering" we are considering to move to Infinispan for many goodies it provides.
> The problem is that some commands that are issued against memcahe infinispan server die with error.
> in ruby application we get errror:
>  ERROR -- : MemCacheError (unexpected response "VALUE views/semantic/1 0 674 \r\n"): unexpected response "VALUE views/semantic/1 0 674 \r\n"
> and in infinispan log I can find:
